McSkillet dead: YouTuber killed in crash after driving McLaren 'in wrong direction at more than 100mph'

Mother and 12-year-old daughter also die after supercar collides with their vehicle

A teenage YouTube star known as McSkillet was among three people killed in a head-on crash on a Californian motorway, police say.

Vlogger Trevor Heitmann, 18, was driving his McLaren supercar at more than 100mph in the wrong direction when it collided with a Hyundai SUV in which a mother and daughter were travelling, according to officers.

All three died following the impact.

The pair in the second vehicle have since been identified as 43-year-old Aileen and Aryana Pizarro, who was just 12.

A number of other cars were also involved in the crash, which happened near San Diego at about 4.30pm local time on Thursday.

Witnesses told police the £400,000 sports car was travelling at high speeds, and had been going southbound in a northbound lane on the Interstate 805 road.

One motorist, Hector Puga, told NBC News he saw the vehicle swerve and explode. “All I could do was hold on to my steering wheel and run over everything that exploded,” he said.

The sports car was reportedly also involved in an earlier incident in which it drove into the fence of an elementary school, but no one was injured.

The son of victim Ms Pizarro described his mother and sister to CBS News as the "kindest, most caring people in the world".

Mr Heitmann was known online as the King of Skins for designing and selling custom content, or skins, which changed the look of in-game characters in first-person shoot-em-up Counter Strike: Global Offensive.

He had almost 900,000 subscribers on YouTube and hundreds of thousands of followers on Twitter.

But reports say he was banned by the game's owner, Valve, earlier this year over a crackdown on gambling involving custom content.

He had not uploaded a video to his channel for almost half a year.

Friends of the YouTuber said online that he had been struggling with his mental health before the fatal crash.

Officials say they are investigating the crash.
