A popular gaming YouTuber known as McSkillet was among three people killed in a head-on crash in California on Thursday, police have confirmed.
Trevor Heitmann, 18, was best known for playing Counter Strike and designing and selling custom content online.
Police say his McLaren sports car was driving at high speed in the wrong direction near San Diego.
The vehicle collided with a Hyundai SUV car with a mother and daughter inside, killing them both.
The pair were later identified as 43-year-old Aileen and Aryana Pizarro, who was 12.
A number of other cars were also involved in the crash, which happened at about 16:30 local time (23:30 GMT).
Witnesses told police the McLaren had been travelling at over 100 mph (160km/h) at the time, and was driving southbound in a northbound lane on the Interstate 805 road.
The sports car was also involved in an earlier incident where it drove into the fence of an elementary school but no one was injured.
