SAN ANTONIO – He sped away after ramming into a police car and crashed head-on into a car occupied by a family of five on Father's Day 2013, killing a couple and two of their children.
George Munoz is on trial facing felony murder charges in those deaths.
Wesley Lindsay, his wife, Kathy Castillo and the couple's children Edward, 7, and Devon, 3, were killed. A third child in the car survived.
"We tried a mask to assist in breathing but it wasn't able to get any air in," SAPD Officer Jonathon Harris testified during Munoz's trial on Wednesday. He was among the first officers on the scene of the wreck.
He said that he and other officers tried to save the lives of the victims by administering first aid until EMS units arrived.
"He had a heartbeat, was breathing and shaking heavily and was unconscious and wasn't responding," Harris testified, his voice breaking at times.
Though it has been over two years since the accident, the emotions for Officer Harris were apparently still very raw.
If Munoz is convicted of felony murder, he is facing 15 to 99 years to life in prison.
Testimony will resume on Thursday in Judge Sid Harle's 226th District Court.
