Police arrested a 66-year-old man Monday after a fatal shooting in Pharr.

At 4:56 p.m. Monday, officers responded to the 400 block of East Egly Avenue, according to a news release from the Pharr Police Department.

The preliminary investigation indicated a 66-year-old man shot a younger man during a disturbance involving a woman, according to the news release.

Both the 66-year-old man and the younger man were romantically involved with the woman — the 66-year-old man is her ex-husband and the younger man is her ex-boyfriend, according to the news release, which didn’t identify the woman.

Justice of the Peace Jaime “Jerry” Muñoz pronounced the younger man dead at the scene.
