SAN ANTONIO -

Police say alcohol might have been a factor in a three vehicle accident early Sunday morning.

It happened on Highway 90 and Nogalitos around 3 a.m.

A red car then slammed into the Tahoe.

Two of the drivers were taken to the hospital to be checked out.

The driver of the red car was detained at the scene.  A gun was found inside his car.

Police believe all three drivers might have been under the influence of alcohol.
