A teenage Youtube star has been killed in a car crash after driving 100mph down the wrong side of a motorway in California.

Trevor Heitmann, an online star who called himself McSkillet, was reportedly driving faster than 100mph when his £200,000 McLaren sports car crashed head-on into an SUV, killing its driver and passenger.

A 43-year-old San Diego woman and her 12-year-old daughter, who were travelling in the Hyundai SUV, died in the incident, the Medical Examiner’s Office said on Friday.

The California Highway Patrol and San Diego Police Department identified the sports car driver as 18-year-old Heitmann.
