Dixon, however, was still pursuing a civil lawsuit against the former Indianapolis Colts wide receiver, said Dixon's attorney, Robert Gamburg.
Although eyebrows raised yesterday when word leaked that Dixon was shot on Girard Avenue near 28th Street, just two blocks north of Harrison's bar, Playmakers, investigators said they had no evidence to suggest Harrison's involvement and had no suspects, sources said.
Detectives were unable to interview Dixon, who was admitted to Hahnemann University Hospital in critical condition and rushed into surgery.
Dixon did, however, tell an officer at the scene of the shooting that he believed that the gunman had been hired by someone else, sources said.
Investigators have not determined a motive for the shooting Dixon, 33. He was convicted in 1998 on drug-possession charges.
Lt. Frank Vanore, a police spokesman, said that police were called to 28th and Girard at 10:59 a.m.
The gunman - identified only as a 6-foot-tall black man who wore a dark-colored hooded sweatshirt, blue jeans and white sneakers - had apparently circled around the Camry and then opened fire while Dixon sat in the driver's seat, Vanore said.
Cops found numerous bullet fragments, apparently fired from a 9mm handgun, littered around Dixon's car, which was parked in front of a Valu-Plus store. The car's windows were shot out.
Vanore said that the gunman fled on foot. It was unclear if surveillance cameras - including two affixed to the front of Valu-Plus - captured the shooting.
Investigators said that Dixon may have been in the area because he regularly eats breakfast at Chopstick & Fork, a sandwich shop next door to Valu-Plus.
"We heard the shots," said a Valu-Plus employee who declined to be named.
