Eighteen-year-old Trevor Heitmann, aka McSkillet, was reportedly driving the wrong way on a San Diego highway at 100 mph when he hit the vehicle carrying the family, the San Diego Police Department said. Both cars burst into flames.
The crash led to a multi-car pileup on Interstate 805.

Heitmann is believed to have been involved in a separate incident at an elementary school earlier in the day as well, according to the California Highway Patrol. No one was injured in that case.
Heitmann's family said in a statement that they are "devastated" by his loss, adding that they are working to determine what happened.
"We want to thank the first responders for their valiant efforts and dedication," the statement read, according to CNN. "We are piecing together the facts and circumstances that lead to incomprehensible tragedy."
The statement added: “We express our deepest condolences to the Pizarro family and anyone impacted by this incident.”
The mother and daughter were identified as Aileen Pizarro, 43, and Aryana, 12, the San Diego Union Tribune reported.
"She was a girly-girl, but she was also tough,” Dominic Pizarro, 22, said of his sister during an interview with the paper. “She was alive with energy."
He added that his mother was a passionate therapist.
“She loved to work with [patients] and tell them they were worth something,” Dominic said.
The family has started a GoFundMe page in memory of the two.
