A 52-year-old woman was taken into custody at Mercy Hospital of Philadelphia yesterday morning, shortly after her common-law husband died there from a stab wound he suffered at her hands, police said.

It was one of three homicides early yesterday in Philadelphia.

A domestic dispute allegedly led to the woman stabbing her 65-year-old boyfriend of 10 years once in the torso about 12:45 a.m. at the home they shared on Paxon Street near Kingsessing Avenue in Southwest Philadelphia, Homicide Lt. Mark Deegan said.

The victim, whose identity was withheld pending notification of kin, was pronounced dead at 12:52 a.m. at Mercy, said Officer Jillian Russell, police spokeswoman.

The woman, whose identity also was being withheld, was taken into police custody at Mercy shortly after the man's death and was officially charged with murder yesterday afternoon.

About a mile-and-a-half away, and about an hour after that slaying, a small-business owner was fatally shot during a robbery on 65th Street near Paschall Avenue in Southwest Philadelphia, Deegan said.

The 30-year-old man was just steps away from the Super Wings restaurant he owned and the adjoining upstairs apartment he lived in when he was confronted by two men on the street about 1:47 a.m., police said.

The victim, whose name was withheld pending notification of kin, was shot twice in the chest when he wouldn't comply with the robbers' demands, Deegan said.

In the end, the robbers got away with nothing.

The restaurant owner was pronounced dead at the Hospital of the University of Pennsylvania at 2:08 a.m., Russell said.

The bloody morning began at 12:25 a.m. when a man was found dead on Colorado Street near Dauphin in North Philadelphia.

Peter Styles, 26, was shot once in the chest in front of his residence, Deegan said.

He was pronounced dead at Temple University Hospital at 12:38 a.m.
