Police are investigating after a woman was fatally shot and her teenage nephew injured outside a home in Brooklyn.

Relatives say Carrie "Audrey" Johnson, 51, pictured below, was visiting her family on Clifton Place, when she went outside around 9:30 last night with her nephew to try to help break up a fight.

According to family members, Johnson's niece's boyfriend was being pistol whipped by several men on the block and she tried to intervene.

Residents say they heard arguing in the street and then gunshots.

Johnson, who lived in New Jersey, was struck in the head and was pronounced dead on the scene.

"She's very progressive person in the community, and this is really a sad time on this block,” said one neighbor. “To have someone like her, an innocent person, she's a victim, I know, of senseless gun violence."

"She's a beautiful person; she's somebody who's going to be really missed," said family friend Glenn Luke. "I loved her."

Daniel Johnson, her 14-year-old nephew, was shot in the leg and taken to Kings County Hospital. He is listed in stable condition.

"My sister and my son getting shot, I'm not feeling good at all, not at all,” said Daniel’s father, Michael Johnson.

"It always happens when it's not intended for the person who really gets it, the wrong person always gets it, and it's a sad thing,” said Johnson’s friend Gary Bolden.

Family members say Johnson once had a relationship and a child with former NBA star World B. Free, who played for the Philadelphia 76ers and now works in public relations for the team. The team says he extends his condolences to her family and friends.

"I don't know the boys' faces that did it, but if you're out there, turn yourself in," said Jeromeka Johnson, the victim's niece. "You shot an innocent lady. That's killing somebody. You go to jail for that. I hope the cops find him. I really do."
