Jeffrey Ramirez, 45, was allegedly witnessed by an off-duty Tracy firefighter driving a 1989 Ford Mustang “erratically” on westbound Grant Line Road between Corral Hollow and Naglee roads, according to Adam Shelton, spokesman for the California Highway Patrol Tracy office.
The witness said Ramirez was allegedly swerving in the roadway, and nearly hit other vehicles, Shelton said.
Other witnesses told police that around 5:35 p.m., Ramirez drifted off Grant Line Road, west of Byron Road, for unknown reasons.
His car then collided with a brick pillar on the north side of the roadway, according to Shelton.
Ramirez was taken by medical helicopter to Doctors Medical Center in Modesto where he was pronounced dead an hour later.
Shelton said the cause of death is being determined by the Stanislaus County Coroners office, and a toxicology report is being run to determine his blood-alcohol levels.
