HOUSTON (AP) — A man who fatally shot his pregnant ex-wife and her boyfriend in the parking lot of a Houston soccer park as children played in a tournament was later found dead from a self-inflicted gunshot, authorities said.

The Harris County sheriff's office said that deputies arriving at the soccer park Sunday morning found a 29-year-old man shot to death and his 38-year-old girlfriend wounded. Sgt. Ben Beall of the Harris County sheriff’s office said that the woman was taken to a hospital, where she and her unborn child were pronounced dead.

The sheriff's office said witnesses told investigators that the woman's 42-year-old ex-husband had been watching one of their sons play soccer when he saw his ex-wife and her boyfriend in the parking lot, walked up to them and shot them both multiple times with a revolver.

Authorities say the ex-husband then walked to his vehicle and drove away.

About two hours later, officials responding to a call about a possible suicide found a man believed to be the ex-husband dead from an apparent gunshot wound behind a home, the sheriff's office said.

The names of the victims and suspect have not been released, pending confirmation by the Harris County Institute of Forensic Sciences.
