Galveston police say the wreck happened at 11:36pm at 40th street along Seawall Boulevard.
The Galveston Police Department, in a post on Facebook this afternoon, said they found the wrecked cars -- a Chevrolet Impala and a Dodge Journey -- in the sand.
Galveston police say the Impala driver was alive and identified as 34-year-old Katy resident, Gerado Flores. The driver of the Dodge Journey, 54-year-old Galveston resident Rosalinda Bruno, died at the scene.
Investigators say Flores was traveling westbound in the Impala on Seawall Boulevard, but was driving in the eastbound lanes. Police say witnesses noted that Bruno was legally parked when Flores drifted over in the parking lane and struck her vehicle, head on, causing both cars to fly off the seawall.
Gerado Flores was transported to the UTMB John Sealy Hospital where he is receiving treatment for non-life threatening injuries.
Flores is charged with manslaughter. He'll be held in the Galveston County Jail. His bond is set at $75,000.
