An Ohio man has been charged with four counts of aggravated murder in the shooting deaths of four people, including his father, sister, and nephew.

Martin Muniz, 41, also allegedly shot the 8-year-old daughter of the fourth fatal victim. The girl was still hospitalized in critical condition on Sunday after the shootings Friday night.

The criminal complaint says that Muniz shot all five victims in the head shortly after 7 p.m. on Friday, WOIO reported. About 40 minutes later, he flagged down police officers and told them about the shooting and where to find the victims.

Muniz’s sister, Angelic Gonzalez, 34, their father, 69-year-old Miguel Gomez, and Angelic’s 16-year-old son Jayden Baez were pronounced dead at the scene. Anthony Boothe, 48, and his daughter were taken to Metro Health Medical Center after the shooting. Boothe died over the weekend, the Cuyahoga County Medical Examiner’s Office said.

“We believe preliminarily that it’s domestic related,” Cleveland Police Chief Wayne Drummond said at the scene. “Our hearts go out to the family, the relatives and so forth and it’s currently under investigation.”

James Box, a family friend, told WOIO that Muniz spent two decades in prison and may have suffered from mental issues.
