Police said Valery Leah Santos, 16, was driving a 2004 Mitsubishi Lancer with her friend Emily Luna, 14, sitting in the passenger seat.

According to the arrest report, Santos began to make a left turn onto Northwest 18th Avenue when Dedieu crashed his pickup truck into the right side of Santos’ car, causing it to rotate violently while being redirected in a northwest direction.

“The force of the impact caused (Santos’) vehicle to also become partially airborne traveling onto the north sidewalk where it collided with the concrete wall of a private business,” the arrest report stated.
