SANANTONIO -- The Bexar County Sheriff's Office confirmed a major accident on Loop 1604 and FM 1518, between La Vernia Road and Highway 87, Friday night.
The accident happened just before 9 p.m., causing Loop 1604 to be shut down temporarily.
Authorities said two people were riding a motorcycle, traveling south on Loop 1604, before colliding with a white Ford truck. Then, a brown Chevy truck equipped a 'lift kit' struck the couple from behind.
BCSO spokesman Paul Berry confirmed both the driver and passenger on the motorcycle died at the scene.
Authorities said both trucks involved in the accident fled from the accident. The white truck may have extensive damage to its front end, according to investigators.
