(NBC News) — A federal jury in Florida has found Tesla negligent in a 2018 crash that killed two teens and found one of the teens 90% responsible for his role in the collision.

Plaintiff James Riley, the father of one of the teens, alleged Tesla was responsible for the death of his son, 18-year-old Barrett, because batteries installed in the 2014 Model S sedan the teen was driving ignited after the electric car crashed in Fort Lauderdale, Fla. while traveling at 116 mph.

Riley said Barrett and the other crash victim, 18-year-old Edgar Monserratt Martinez, initially survived the collision when the Tesla’s airbags deployed but died after the car caught fire.

Riley also claimed a Tesla technician had, without his consent, removed a speed limiter the family had installed on the car.
