As actor Anton Yelchin, best known for playing Ensign Pavel Chekov in the Star Trek reboots, left his house on June 19, 2016, he pulled his Jeep Grand Cherokee out of the garage and drove toward the security gate at the bottom of his steeply inclined driveway. He placed the car in what he believed was "Park" and exited the vehicle. Investigators later determined the vehicle's electronic "monostable" shifter had actually left the car in Neutral. As Yelchin walked toward his gate, the 2.5-ton Jeep rolled backward down the slope. Before he could react, the rolling vehicle pinned him against a heavy brick mailbox pillar attached to his security fence. The Los Angeles County Coroner determined he died within roughly one minute of impact. His official cause of death was listed as blunt traumatic asphyxia.
