JACKSONVILLE, Fla. -

Police have arrested a second man in connection with a quadruple shooting in which three people were killed outside an apartment complex Tuesday night in the New Town neighborhood, Channel 4 has learned.

Richard Dixon, 25, is charged with possession of a weapon or ammunition by convicted felon. Theodist Richardson, 20, was arrested early Wednesday morning, hours after the shooting. He is charged with two counts of murder, one count of aggravated battery and one count of firing into an occupied dwelling.

Police said Thursday evening they are no longer looking for a second suspect in this case.

A memorial is growing outside the Prince Street apartment complex for the victims. There is encouraging news for the only survivor, 16-month-old Marc Smith, who doctors said is now in good condition after undergoing surgery Tuesday night. He returned home Thursday afternoon.

Also Thursday, Marion Burton tied balloons to a tree outside the apartment complex where his 19-year-old daughter-in-law, Danielle Melton, was hit by a stray bullet while she was sitting outside of her first-floor apartment Tuesday night. Melton later died at a hospital.

Police said she was caught in the middle of gunfire between rival drug dealers.

"She's got two little baby twin boys and just lost her daughter two years ago. It's devastating to everyone who knew Danielle," Burton said.

Police said 26-year-old Kenneth Curry and 31-year-old Billy Johnson died at the scene.

Investigators said Richardson and Curry began shooting at each other after a confrontation that followed a pistol whipping that occurred during a recent drug deal.

"They fighting over turf. Who's going to sell over here at that corner, at this corner, but the major thing is we need to come together in the community," said resident Janice Williams, who's concerned about violence in the area.

Williams calls it a sad reality in her neighborhood.

As for the 16-month-old, those in the community are still shocked that a stray bullet hit such a young, innocent victim.

"How could someone see a baby, a baby in their streets or in their house, and fire a firearm at a child?" Williams said. "That child may not have been the target, but the child was hit."

"It's sad, kids getting shot, not even a year yet," said resident Tony Carway. "The lady (Melton) got killed. She wasn't even around here for two months yet."
