A Brownwood man was killed Tuesday morning when the pickup he was driving overturned on U.S. Highway 377 near Winchell.

A motorist from Brady who stopped to help was injured when an 18-wheeler crashed into the accident site, and the rig’s driver was arrested on a charge of intoxication assault, Texas Department of Public Safety Trooper Tom Nipper said.

Joseph Zapata, 23, was killed in the accident, which happened around 6:45 a.m., Nipper said. He was pronounced dead by Justice of the Peace Walter Croft.

Zapata was driving south in a 2003 Chevrolet Silverado when the pickup left the road, then overturned when Zapata over-corrected and slid to a stop on its roof, Nipper said. He said Zapata was partially ejected and did not appear to have been wearing a seat belt.

Two motorists stopped to help, and Roy Smith of Brady was trying to wave down traffic with a flashlight, Nipper said. A northbound cattle hauler grazed Zapata’s pickup, which was knocked into Smith.

The rig’s driver pulled to the right and stopped, and the driver, Owen Ogle, 53, of Oklahoma, was arrested on suspicion of being under the influence of drugs, Nipper said.

Authorities said Smith was flown by helicopter ambulance to Hendrick Medical Center in Abilene, but hospital officials there did not have a record of him Tuesday afternoon. Nipper said Smith did not appear to have life-threatening injuries.

Assisting in the investigation are Trooper Karl Keesee, Trooper Mike Haley, Trooper Larry Dunkin and Sgt. Jason Shea.
