He collided with a Hyundai driven by a 43-year-old woman who was with her 12-year-old daughter.
A witness told police that a driver, later identified as Trevor Heitmann, 18, was traveling the wrong way in a carpool lane at 100 miles per hour when he collided head-on with an SUV, killing Aileen Pizarro, 43, and her daughter, Aryana Pizarro. Heitmann's classmates also identified him to Fox San Diego as the driver who caused the crash.
About 30 minutes prior to the fatal crash on I-805 HOV, Trevor Heitmann was also allegedly spotted driving his auto through the gates of Ashley Falls Elementary School in San Diego.
The teen was behind the wheel of a 2014 McLaren that was traveling south in the carpool lane of the northbound 805 around 4:35 p.m. when his vehicle slammed head-on into an SUV, authorities said.
According to the Los Angeles Times, a person who called 911 to report the crash said, "The whole northbound side [of the freeway] is on fire". His last video appeared to have been posted some five months ago.
"Although Trevor Heitmann never used his real name or showed his face on his gaming channel, he showed off the black McLaren 650S he reportedly drove during his supposed suicide attempt, boasting that it could "[beat] just about every other top supercar" in a drag race.
Thirty minutes before the crash, Heitmann crashed thrugh the gates of a Carmel Valley elementary school, the station reported. Trevor had a skin estimate that was worth around $100, 000, according to the Mirror, but other sales and the large audience of his YouTube channel, most likely made him much more.
Friends of the YouTuber online said on social media that he had been struggling with his mental health before Thursday's accident. In a statement issued to CNN, Ashley Falls School "a auto drove through the side gate and an individual got out of the vehicle and threw an item at a door, breaking a window".
