Authorities on Monday announced the identities of the two teens. 17-year-old San Rafael resident Lorena Recendez-Martinez was driving the vehicle and 16-year-old Los Angeles resident Amada Guadalupe Salinas-Agular was a passenger in the 2018 Mercedes Benz Coupe, according to public safety officials.

It is unknown if alcohol or drugs were a factor in the collision.

Investigators believe the Mercedes was travelling at a high rate of speed west on Golf Course Drive when it struck the right curb while trying to negotiate the curve in the roadway.

The car then jumped over the curb and hit two street signs and two trees, ultimately hitting a traffic signal and coming to rest.

Based on the evidence as well as statements from an eye witness to the collision it was a solo crash.
