A driver and his passenger died Saturday morning when the car they were in left the highway and hit a tree in Winston County, authorities said Monday.

Refugio Sosa, 47, of Haleyville, was driving a 2001 Ford Mustang around 7:18 a.m. Saturday on Highway 278 when the vehicle left the road and struck a tree, said Alabama Law Enforcement Agency Senior Trooper Cody Farrar.

Sosa and a passenger in the Mustang, identified as 50-year-old Haleyville resident Luis E. DeLion Castro, were pronounced dead at the scene of the wreck about five miles west of Double Springs, Farrar said.
