Steve Jaramillo was driving a Ford F-150 southbound on Alma Drive at what police described as a high rate of speed when he struck a Toyota RAV4 around 7:15 p.m. near the intersection of Alma Drive and Cross Bend Road, according to the Plano Police Department.

The RAV4's driver had been heading north on Alma Drive and was attempting a left turn onto the westbound side of Cross Bend Road on a flashing yellow light when the collision occurred, police said. The impact caused the RAV4 to roll onto its right side, and both vehicles struck a traffic signal pole and a tree at the intersection.

When officers arrived, they found the two occupants of the RAV4 unconscious. Plano Fire-Rescue crews extricated both people and performed life-saving measures, but both victims died at the scene.

Police said they believe alcohol and speed were contributing factors in the crash. Jaramillo was arrested and charged with DWI. The department said additional charges will be considered as the investigation proceeds.

Authorities have not released the identities of the two victims, citing the need to notify next of kin.

The intersection of Alma Drive and Cross Bend Road sits in a busy residential and commercial corridor in Plano, where flashing yellow left-turn signals are common. Under Texas law, a flashing yellow arrow means a driver may turn left after yielding to oncoming traffic; police allege the pickup's excessive speed and the driver's intoxication prevented that yield from being possible.

Plano police are continuing to investigate the crash and ask anyone with information to contact the department.
