Officers from Southwest Philly's 12th District responded to a shooting call and found Jett lying on the sidewalk at Grays Avenue and 62nd Street at 5:52 p.m. Friday, police said.
Clark said investigators determined that a gunman had walked up behind Jett and fired numerous shots into his back at point-blank range before running. Jett, whose father, according to police sources, is a bicycle-patrol officer in Center City's 9th District, died a short time later at the Hospital of the University of Pennsylvania.
Fifteen minutes after Jett's killing and just three blocks away, at Buist Avenue and 61st Street, police said Benjamin Collier, 24, also was fatally shot three times in the chest. It was originally believed that the homicides were connected, but police said yesterday they were determined to be isolated shootings.
"The more and more we are looking into it, even though they happened blocks apart, it does not appear, right now, that there is any connection," Clark said.
No arrests had been made as of last night. Tipsters should contact the Homicide Unit at 215-686-3334.
