Allegheny County detectives say a Wilkinsburg man fatally stabbed Charles Pullie in North Braddock Sunday night after confronting him over an argument with a woman.

Carl Harrison, 57, is charged with a single count of criminal homicide.

Pullie, 38, of Pittsburgh was stabbed at least once in the abdomen and pronounced dead soon after midnight on Monday during surgery at UPMC Presbyterian Hospital, according to a criminal complaint.

Police said Pullie had been arguing with a North Braddock woman, who was not named in the complaint, at her house on Grove Way close to Monongahela Cemetery.

The relationship between Pullie and the woman was not made clear in court paperwork.

At the time of the argument, the woman was on the phone with her 17-year-old child, who lives with Harrison.

Harrison is described in the complaint as a “friend and former paramour” of the woman.

The child asked Harrison to check on the woman, according to the complaint.

Harrison, who arrived with a purple-and-white folding knife, confronted Pullie, police said the woman told them.

Both men briefly argued then left. The woman told police she then heard Pullie outside calling for help.

She found him bleeding in a nearby vacant lot behind the 1100 block of 4th Street, according to the complaint. Harrison was gone, the complaint said.

Police said they found what appeared to be blood on the front porch and door of the woman’s house.

The juvenile told police that Harrison had called them around 9:23 p.m. to say he had a fight with Pullie.

Harrison returned to their Wilkinsburg apartment about 15 minutes later, according to the complaint.

There, Harrison told the juvenile he stabbed Pullie after finding the juvenile’s mother with an injury to her back.

Police contacted Harrison, who spoke with detectives at Allegheny County Police headquarters.

Harrison initially claimed he had never interacted with Pullie, the complaint said.

Harrison told police he had arrived at the woman’s home after she called to say she had been in an ongoing altercation with Pullie on Sunday, the complaint said.

Harrison had visited the house earlier Sunday afternoon to drop off a gift for the woman, the complaint said.

When he returned to the house around 9 p.m., he said he found the woman with a large gash on her back that he believed was the result of an altercation with Pullie, the complaint said.

After detectives confronted Harrison with the timeline and witness statements, however, police said he admitted to arguing with Pullie but denied stabbing him.

A date has not yet been set for Harrison’s preliminary hearing. Court documents did not include bail information.
