Report: Man shoots ex-girlfriend, her current boyfriend, then kills himself in Chicago

An argument on the Northwest Side ended with two people shot and one man dead in an apparent suicide Tuesday in Gladstone Park, according to police.

Ramon Medoza-Maguellal, 37, was arguing with a man and a woman about 8:50 p.m. in the 5500 block of North Monitor Avenue when he shot them both, Chicago police and the Cook County medical examiner’s office said. He then apparently shot himself.

Police said the incident was domestic-related. Medoza-Maguellal -- who lived in the Albany Park neighborhood -- was pronounced dead on the scene, authorities said.

An autopsy Wednesday found he died of a gunshot wound to the head and his death was ruled a suicide, the medical examiner’s office said.

The wounded pair were taken to Lutheran General Hospital in Park Ridge in good condition, police said. The woman, 48, was shot in the arm, and the 29-year-old man was shot in the shoulder.

Officers recovered a weapon on the scene, police said.

There was a report that claimed the gunman was an ex-boyfriend, and that he shot his ex-girlfriend and her current boyfriend before killing himself.

Area North detectives are investigating.
