JACKSONVILLE, Fla. -

A man sitting on the front porch of a Northwest Jacksonville home was killed late Wednesday night in what Jacksonville police describe as a drive-by shooting.

Police said two men were walking down Blue Avenue at West 10th Street at about 11:30 p.m. when people inside a vehicle shot at them. They said the pedestrians fired back. During the exchange, 32-year-old Frank Harrity, who was visiting a nearby home, was struck and killed in the crossfire.

Police don't know how many bullets struck Harrity, who was pronounced dead at Shands Jacksonville Medical Center shortly after the shooting.

Police believe the bullets that struck the victim came from the vehicle.

Jacksonville Sheriff's Office spokesman Shawn Coarsey said police don't know why the pedestrians were targeted by the people in the vehicle.

Police didn't release a description of the vehicle, only to say it was a dark color.

Frank Harrity Investigators said two of Harrity's friends witnessed the shooting from the porch.

"It's just sad people are going around just shooting," said family spokeswoman Beverly McClain, of Families of Slain Children.

Harrity (pictured, right) grew up around the corner from where he died and worked as a lawn man.

"He was loved by his family and friends and his neighbors," McClain said. "Everybody's rallying around his family right now."

McClain said Harrity's family wants to know why he was killed, and they want the shooter arrested.

"They're seeking answers. They're asking the community to step up and do the right thing," McClain said. "Sheriff (John) Rutherford gets his man. You can't come through Jacksonville and do something and don't get caught."

No arrests have been made.
