FBI taps Tesla Sentry Mode footage to help catch man behind alleged hate crimes
It appears that some members of the Federal Bureau of Investigation (FBI) are now becoming familiar with Tesla’s built-in security features like Sentry Mode, which allows vehicles to record videos from their cameras to actively monitor their surroundings. This was undoubtedly the case in an incident back in December, which involved slashed tires, arson, and what appears to be a racially motivated attack against a church.Â
In an affidavit dated April 15, 2021, FBI Special Agent Casey Anderson outlined the events that led to an incident that resulted in the destruction of the Martin Luther King, Jr. Community Presbyterian Church in Springfield, Massachusetts. The suspect behind the incident, 44-year-old Maine resident Dushko Vulchev, is a naturalized United States citizen from Bulgaria. As per the FBI agent’s affidavit, Vulchev had previously run afoul of the law prior to his apparent arson in December, having been convicted of threatening a foreign official in 2015 and a series of offenses such as domestic violence assault in 2017.Â

The Attacks
In December 2020, the MLK Church experienced a series of fires, one of which eventually destroyed the whole building. The first of these fires were reported on December 13, when the fire department was deployed to extinguish a blaze behind the church. On the same day, a vehicle had its tires slashed two miles away from the church. The next day, a BMW about 1.5 miles away from the MLK church and a Tesla parked less than a mile away from the church had their tires slashed. In the case of the Tesla, its owner found that one of the vehicle’s wheels was also missing.Â
Another fire behind the Martin Luther King, Jr. Community Presbyterian Church was set on December 15, 2020, at around 6:32 p.m. The Springfield Police Department (SPD) Arson and Bomb Squad investigated the fire and promptly determined that the blaze had been intentionally ignited. Interestingly enough, another fire in the church was reported at 11:03 p.m. that same day. Upon investigation, the SFD reported that the blaze had been “intentionally set to eventually involve the structure” of the church.Â
Things essentially calmed down until December 27, when a Dodge Charger had its tires slashed just 400-500 feet away from the MLK Church. At around 5:06 a.m. the next day, the American International College campus police reported a new blaze at the MLK Church. This time, the fire was started just outside the basement side door, where it burned through and up through the church’s main floor. The blaze essentially destroyed the church, and upon investigation, the SPD concluded that the fire was intentional.Â

The Investigation
Investigators working on the case were able to obtain several video footage relevant to the case. In the first tire slashing incident on December 13, footage from the City of Springfield recorded a gray Chevy Cruze pulling up into the same parking lot as the vehicle that was attacked. The car was found to have been registered to the suspect, Vulchev. City video footage captured the suspect crossing the street in the direction of the MLK Community Center later that day. The gray Chevy Cruze was also recorded circling the MLK Church.
Vulchev’s Chevy Cruze was sighted by city video footage once more the next day, when the BMW tire slashing incident transpired. As per the FBI agent’s affidavit, a while male matching Vulchev’s height, gait, and clothing, was spotted approaching the BMW. Later that day, a Tesla became the next victim of the suspect’s tire slashing tendencies. But this time around, the special agent didn’t just have a faraway shot of a man approaching a vehicle. This time around, authorities were able to get a clear shot of Vulchev as he was slashing and stealing the Tesla’s tires and stealing a wheel, thanks to Sentry Mode. Tesla’s built-in cameras even captured the suspect putting the stolen goods inside his trunk.Â
Special Agent Casey Anderson related his experience with Teslas and their built-in cameras in his affidavit. “Based on my training and experience and this investigation, I am aware that the Tesla referenced above is equipped with cameras at various points around the body. ATF Special Agent Marc Maurino (“SA Maurino”) and I have reviewed video footage retrieved from the Tesla showing an individual that I can identify as Vulchev, based on my observation of Vulchev during the Vulchev PPD Interview.Â
“The video footage from the Tesla shows Vulchev at a close distance crouching near the Tesla and using a tire iron to remove the wheels. Additional Tesla video footage captured Vulchev removing one of the Tesla’s wheels and placing it in the trunk of Vulchev’s car. Vulchev’s face is clearly visible in the video. Vulchev was wearing grey pants and a dark-colored sweatshirt, Adidas three-stripe sneakers, a black hat with two grey stripes, and light-colored work gloves, the agent noted in his affidavit.Â
Vulchev and his vehicle were spotted around the MLK Church fires, as well as subsequent tire slashing incidents.Â

The Arrest
On December 30, 2020, a complaint about a vehicle driving erratically was reported to authorities. When provided with the license plate of the vehicle in question, it was determined that the car was Vulchev’s. Police stopped the suspect’s vehicle on suspicion of erratic driving and possible links to the multiple tire slashing incidents. Since they were aware of the ongoing federal investigation into the fires against MLK Church, local authorities promptly contacted FBI Supervisory Special Agent of the Springfield Resident Agency Matthew Fontaine.Â
Special Agent Fontaine arrived at the scene of the stop, and upon initial investigation, the FBI agent noted that the suspect may have been living in his car for some time. The FBI agent spoke with the suspect for about eight minutes outside, and immediately, Fontaine noted that Vulchev was wearing the sneakers that were captured clearly by Tesla’s Sentry Mode. PPD officers initially released the suspect, though he was arrested the day after over his links to the multiple tire slashing incidents and the Martin Luther King, Jr. Community Presbyterian Church fires.Â
On January 4, 2021, the FBI and ATF conducted a search of Vulchev’s vehicle, where they found a computer, a hard drive, and several USB storage devices. A search of the computer revealed Vulchev’s shocking racially charged stance against non-white people. This was seen in messages to an ex-girlfriend—who currently has a lifetime protective order against Vulchev—which featured numerous slurs against Muslims and blacks. Vulchev’s apparent hate against non-whites was notable, as seen in a message to his ex-girlfriend where he was complaining about the race of ABC’s The Bachelorette. A search of the suspect’s phone revealed photos of several notable items, such as a firearm, an image of Adolf Hitler in an Adidas tracksuit, and a “White Lives Matter” mural, as well.Â
With these in mind, FBI Special Agent Casey Anderson noted that there is probable cause to believe that Vulchev committed damage to religious property, which is in violation of 18 USC §§ 247(c) and (d)(3), and the use of fire to commit a federal felony, which is in violation of USC § 844(h)(1). As per a press release from the US Department of Justice, Vulchev is currently in state custody and is due to make an initial appearance in federal court in Springfield at a later date.Â

Tesla’s Semi truck factory is open with a detail that changes everything
Tesla’s dedicated Nevada Semi factory has opened, targeting 50,000 trucks per year as fleet adoptions accelerate nationwide.
Nearly nine years after Elon Musk unveiled the Tesla Semi in November 2017, the company is now opening a dedicated factory just outside of Reno, Nevada, and ramping toward mass production of 50,000 trucks per year.
Volume production began in March 2026 at the new Tesla Semi factory, with the competitive advantage not being the factory itself. Rather, it’s where Tesla built it. By constructing the 1.7 million square foot facility directly adjacent to Gigafactory Nevada in Sparks, Tesla closed the one supply chain loop that had delayed the Semi program for years. The 4680 battery cells that power the Semi are manufactured in the same complex, which significantly streamlines supply logistics. That single decision eliminates the bottleneck that forced Tesla to prioritize battery supply for passenger cars over the Semi throughout 2020, 2021, and 2022, which is precisely why the first deliveries slipped three years past the original target. Every other electric truck manufacturer sources its battery cells from a separate supplier, ships them to a separate factory, and absorbs the cost and delay that comes with that. Tesla built its Semi factory around its battery factory, and that vertical integration is what makes 50,000 trucks per year a realistic number rather than an aspirational one.
At the 2025 Annual Shareholder Meeting, Musk was direct about where things stood, stating “Starting next year, we will manufacture the Tesla Semi. We already have a lot of prototype Semis in operation – PepsiCo and other companies have been using them for some time. But in 2026, we’ll begin volume production at our Northern Nevada factory.” Full ramp to volume output is targeted before June 30, 2026.

The first limited deliveries happened in December 2022 to PepsiCo, which eventually doubled its fleet to 50 trucks out of its California distribution facility. Since then the Semi has been showing up in more corporate fleets. As Teslarati noted in March, a Ralph’s Supermarkets branded Semi was spotted on a Los Angeles highway, confirming Kroger’s partnership with Tesla to deploy up to 500 electric Semis. Walmart, Costco, Sysco, US Foods, DHL, Hight Logistics and WattEV are among the companies actively running or receiving units. DHL logged real-world efficiency of 1.72 kWh per mile under a full 75,000 pound load over 388 miles, matching Tesla’s targets closely.
The 2026 production model arrives with meaningful upgrades over the original, with a 1,000 pound weight reduction, updated aerodynamics, and support for 1.2 MW Megacharger speeds that can restore 60% of range in around 30 minutes during a mandatory driver rest break. Tesla opened its first public Megacharger in Ontario, California in March, positioned near the I-10 and I-15 interchange serving the Ports of Los Angeles and Long Beach. The company plans 37 Megacharger sites by end of 2026 and 66 total across 15 states by early 2027, with construction beginning at the nation’s largest truck stop operator in the first half of this year.

Musk has described the Semi’s economics as a straightforward case. “The Semi is a TCO no-brainer,” he said, noting the total cost of ownership is “much, much cheaper than any other transportation you could have.” At under $300,000, the truck costs roughly double a comparable diesel, but California’s $200,000 per vehicle subsidy has driven over 1,000 state orders alone. As Teslarati has tracked, the prototype fleet accumulated over 13.5 million miles with 95% fleet uptime before production ever scaled. The factory opening now turns that proof of concept into a production program.

Tesla Full Self-Driving gets first-ever European approval
Tesla owners in the Netherlands with a Full Self-Driving subscription will receive a software update “shortly,” the company said, activating the operation of the company’s semi-autonomous driving tech for the first time in Europe.
Tesla Full Self-Driving (Supervised) got its first-ever European approval, as the Netherlands gave the suite the green light to begin operation.
Tesla owners in the Netherlands with a Full Self-Driving subscription will receive a software update “shortly,” the company said, activating the operation of the company’s semi-autonomous driving tech for the first time in Europe.
The Dutch vehicle authority RDW granted the type approval after more than 18 months of rigorous testing on both closed tracks and public roads. FSD Supervised complies with UN R-171 standards and benefits from Article 39 exemptions under EU Regulation 2018/858. Importantly, it is not a fully autonomous vehicle.
The RDW stressed that the driver remains fully responsible and must maintain attention at all times. “Safety is paramount for the RDW,” the authority stated. “Proper use of this driver assistance system contributes positively to road safety.” Sensors monitor driver alertness, issuing warnings if eyes leave the road or hands are unavailable to take control immediately.
CEO Elon Musk also commented on the approval in a post on X, saying:
“First (supervised) FSD approval in Europe! Congratulations to the Tesla team and thank you to the regulatory authorities in the Netherlands for all of the hard work required to make this happen.”

Trained on billions of kilometers of real-world driving data, FSD Supervised allows the vehicle to handle residential streets, dense city traffic, and highways under constant supervision. Tesla’s post declared:
“It can drive you almost anywhere under your supervision – from residential roads to city streets & highways. No other vehicle can do this.”
The company added that it is “excited to bring FSD Supervised to more European countries soon.”
This national approval paves the way for broader EU adoption. Other member states can recognize the Dutch certification individually, with a potential bloc-wide rollout via European Commission committee vote anticipated by this Summer. The decision underscores Europe’s stricter safety and documentation requirements compared to U.S. self-certification.
Tesla Europe shares FSD test video weeks ahead of launch target
The Netherlands’ approval represents a pivotal step for Tesla in Europe, where complex regulations and mixed traffic have delayed rollout. Musk added that the RDW was “rigorous” in its assessment of FSD.
By proving the system’s safety in one of the continent’s most bicycle- and tram-heavy nations, Tesla positions itself to transform mobility across the EU—delivering greater convenience while keeping drivers firmly in control.
As the first domino falls, anticipation builds for FSD Supervised to reach additional countries soon.

Tesla is using a redesigned Cybertruck battery cell to mitigate Semi challenges
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla revealed that it is utilizing redesigned Cybertruck battery cells in its Long Range Semi to mitigate some pertinent challenges that come with long-haul logistics.
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla’s long-awaited Semi truck is entering production at its Nevada Gigafactory, and fresh factory footage reveals a clever evolution in its battery technology.
The Long Range variant, designed for up to 500 miles of real-world range, relies on a structural battery pack that uses the same 4680-form-factor cells found in the Cybertruck.
However, Tesla engineers have completely redesigned the pack’s architecture—shifting from the flat, pancake-style modules typical in passenger vehicles to a compact, vertical cubic layout. This change isn’t just about cramming more energy into the chassis; it’s a targeted solution to one of electric trucking’s biggest headaches: range loss in cold climates.
Dan Priestley, Head of the Tesla Semi program, said:
“We’re using essentially the same cell out of Cybertruck, but our cars packs are more like a pancake. Whereas these are more like a cube. You get a lot of energy stored in a small space. You can only do this if you design the vehicle to be electric from the ground up.”
Here, in all its glory, is the exclusive first look at the massive @Tesla Semi factory.
Our @corememory crew went to Nevada to see the line come to life, as it gets ready to pump out thousands of all-electric trucks. We saw the new cab and went on a drive too. Wunderbar! pic.twitter.com/a0S5zVEr87

In conventional EVs, battery packs are laid out horizontally in wide, flat arrays to fit under the floor. While this works for cars and even the Cybertruck’s structural pack, it exposes a large surface area to the elements.
Heat escapes quickly, especially overnight when the truck is parked. Cold temperatures slow chemical reactions inside lithium-ion cells, reducing available energy and forcing the vehicle to expend extra power warming the battery and cabin.
Real-world tests on vehicles like the Cybertruck show winter range losses of 20-40 percent, depending on conditions. For long-haul truck drivers operating in Canada, Scandinavia, or the northern U.S., this “silent killer” means unplanned stops, reduced payloads, and higher operating costs.
From personal experience, cold weather still impacts EV batteries even with various inventions and strategies that companies have come up with. In the cold Pennsylvania winter, charging was much more frequent for me due to range loss due to temperatures.
Tesla’s cubic battery pack flips the script. By arranging the 4680 cells in tall, dense vertical stacks, the pack minimizes external surface area relative to its volume—essentially turning the battery into its own thermal blanket.
Factory video from the Semi assembly line shows these large, yellow-green structural modules mounted directly onto the chassis, forming a near-cube shape.
The reduced exposure helps the pack retain heat generated during operation, keeping cells closer to their optimal temperature even after hours in sub-zero conditions.
The design doesn’t stop there. Tesla pairs the cubic pack with an advanced heat pump system that actively recycles thermal energy from the motors, brakes, and even ambient air.

Unlike passive systems in earlier EVs, this architecture transfers waste heat back into the battery, maintaining readiness for morning departures without draining the pack.
Executives have noted that the combination, cubic geometry plus intelligent thermal management, dramatically cuts overnight cooldown and range degradation, making the Semi viable for 24/7 fleet operations in harsh winters.
Beyond cold-weather performance, the redesigned pack integrates structurally with the truck’s frame, enhancing rigidity while simplifying assembly. Production footage shows workers installing the massive modules early in the line, signaling that the Semi’s battery is now a core chassis component rather than an add-on.
Using proven 4680 cells keeps costs down and leverages Tesla’s scaled manufacturing know-how from Cybertruck and Model Y lines.
Tesla’s focus on ramping up Semi output will lean on small innovative steps like this one. Truckers are not immune to traveling in cold weather conditions, and changes like this one will help make them more effective while also increasing output by logistics operators who choose to go all-electric with the Tesla Semi.
