A 14-year-old boy has been charged with murder in the killing of a West Philly rec center employee

A 14-year-old boy has been charged with murder in the shooting death of Tiffany Fletcher, a city employee and mother of three who was fatally struck by a stray bullet while working at the Mill Creek Recreation Center on Friday afternoon.

Makie Jones was arraigned over the weekend after being charged as an adult with murder, firearms violations, and other crimes, according to court records. He was being held in a juvenile detention facility without bail.

Mayor Jim Kenney said Monday that the killing came during a weekend with an “outrageous” level of violence — a stretch in which a 17-year-old was killed while walking her dog, a man was killed while getting groceries, a 64-year-old man was fatally shot on an underground trolley platform, and a SEPTA manager was ambushed and killed outside his home in what police said was a case of mistaken identity.

“It’s just unfathomable to think how many lives were impacted by gun violence,” Kenney said at a news conference, which also featured remarks from District Attorney Larry Krasner, Police Commissioner Danielle Outlaw, and Parks and Recreation Director Kathryn Ott Lovell.

Ott Lovell said as the city struggled this year to hire enough staff to open swimming pools, Fletcher, 41, came to work as a pool maintenance employee — then agreed to stay on after the summer ended to continue working at the rec center, which was two blocks from her family’s West Philadelphia home.

She and others decried that Fletcher was killed doing her part to make her neighborhood safer, with Ott Lovell saying: “Tiffany answered the call each day to serve children and families in her community, and to make her three children and her family proud.”

Fletcher’s relatives said she was “a wonderful mother” as they held photos of her while addressing reporters.

“She loved everybody,” said Fletcher’s niece, Jean Washington-Fletcher. “She’d give you the shirt off her back. She’d give you the food off her table. I just want peace for my aunt.”

The killing came after a shootout around 1 p.m. Friday between Jones and at least three other people near the rec center on the 4700 block of Brown Street, Chief Inspector Frank Vanore said Monday. Vanore said it was not clear what sparked the gunfire, but that investigators later recovered 12 fired cartridge casings at the scene — eight on one side of the street, and four on the other.

Fletcher was struck by wayward shots, then ran to a nearby business, where Outlaw said employees sought to help Fletcher tend to her wounds. Officers who responded took her to Penn Presbyterian Hospital, where she was declared dead later on Friday, police said.

Meanwhile, officers who responded to the scene of the shooting saw Jones running toward Parrish Street and gave chase. They were able to stop him, Outlaw said, and also found a ghost gun in a trash can on the same block.

Outlaw and others on Monday pleaded with community members to provide information that might help identify the other three people involved in the shootout. Police did not describe any suspects or say if they had any specific leads to follow.

“We want to see justice — not just for us but for her children,” said Fletcher’s niece. “Tiffany Fletcher was a good woman to everybody. She was a friend, she was an advocate. And she worked hard to serve our own community, which we grew up in.”

Kenney said: “If we don’t get this information, we can’t move forward. So please, think about what happened in Mill Creek, think about poor Tiffany, and think about how many people around that community know who those other kids are. ... We need your help.”

Jones was being represented by the Defender Association of Philadelphia. A spokesperson declined to comment.

The weekend’s gunfire continued to push the city’s violence levels to unprecedented heights. Through Sunday night, police statistics show, 384 people had been slain in homicides this year — 4% higher than last year’s record-setting pace.
