Philadelphia police detectives met with the city's district attorney's office about a month ago to present their final evidence relating to an April 29 shooting outside a business in North Philadelphia owned by Indianapolis Colts wide receiver Marvin Harrison that injured three people, a source with knowledge of the meeting told ESPN Monday night.
District Attorney Lynne Abraham has scheduled a press conference for Tuesday at 11 a.m. in Philadelphia to announce the results of the investigation.
Police detectives working on the case have been pressing the district attorney for months to bring the investigation to a close, but they recently concluded that the district attorney was not prepared to act until after the end of Harrison's NFL season. The Colts lost in the wild-card round of the playoffs Saturday night in San Diego.
Police detectives have longed believed they had enough evidence to bring weapons charges against Harrison, a source with knowledge of the police investigation told ESPN.com. But witnesses have been less than cooperative with the authorities, sources said, and that has led to uncertainty surrounding the evidence in the case.
A spokesman for the district attorney declined comment Tuesday night.
In May, Philadelphia police detectives told ESPN that six of the bullet casings found after the April 29 shooting on the street corner across the street from Harrison's car wash and garage came from a gun -- a rare, armor piercing Belgian-made pistol -- that Harrison surrendered to police. The police have been intent on solving the case because they want to discourage ownership of such guns.
In interviews with police, Harrison has maintained that he was not involved in the shooting, sources say. But Pennsylvania gun laws specifically state that if Harrison's gun was discharged in the act of a crime, he could be charged -- even if he was not the shooter.
In October, one of the victims of the shooting filed a $100,000 civil suit against Harrison, claiming that he suffered "serious and permanent injuries -- and severe shock to his nerves and nervous system" as a result of the shooting. The alleged victim, Dwight Dixon, claims he was shot in the left hand. Harrison has acknowledged he was involved in a fight with Dixon at Harrison's bar, Playmakers in North Philadelphia, two weeks prior to the shooting, but said he did not have anything to do with the shooting.
"It's our position that Marvin Harrison was the shooter," Dixon's attorney, Robert M. Gamburg, told the Philadelphia Daily News in October.
Harrison's agent, Tom Condon, the NFL and a spokesman for the Colts said they were unaware of the district attorney's conclusions in the case and had no comment.
Harrison's attorney could not be reached for comment.
