Sixteen-year-old Paul Fitzgerald Perry Jr. was riding home on his bike when he was fatally shot.

The Suitland teenager, who went by the nickname "PJ," was a sophomore at Oxon Hill High School, with a loving personality and love of basketball, said his father.

That was 11 years ago. Paul Perry Sr. says he wonders every day what kind of man his son would have grown into, what kind of job he'd be working, what kind of father he'd become.

"You think of the people who did this, more than likely they have children of their own now, and you want to look them in the eye and ask 'Why?' " Perry said. "I'm not full of hate or anger. But I miss my son."

Prince George's County Police Cold Case detectives are asking the public for information that can lead to an arrest and bring some comfort to the family.

"Here's a 16-year-old boy who rides up to an intersection where there are a lot of people coming and going," said Sgt. Richard Fulginiti. "What we're looking for is anyone who may have seen or heard the incident."

Perry Jr. was shot in the head near the intersection of Audrey Lane and Maury Avenue in Oxon Hill where he grew up, shortly after midnight on July 16, 2001. Police found the teenager dead next to his fallen bike.

Witnesses told police that they saw Perry at the corner on his bike, talking to a male. They then heard a gunshot and saw a male running from the scene.

A woman said she heard gunshots and then friends of Perry's yelling and crying.

Anyone with information is asked to contact the Cold Case Homicide Unit at 301-772-4925 or Crime Solvers at 866-411-TIPS (8477).
