A Brooklyn man went from peacemaker to murder victim after breaking up a scuffle between his sister and a woman she was feuding with, heartbroken relatives said Wednesday.

Shamar Davis, 21, stepped in to defuse what his aunt called a “girl fight” between his sister and a friend of a neighbor — and paid for the good deed with his life, his devastated aunt Karen Davis told the Daily News.

Hours after he intervened in the long running feud between the two women, a vengeful gunman came to blow him away in the hallway outside his family’s 13th-floor apartment in Brownsville’s Tilden Houses.

“I love my nephew with (all) my heart,” Davis said. "He’s like my son that I never had.”

The shooter was lying in wait Monday night after Shamar’s sister’s rival went to the Bronx to tell her “baby daddy” about Shamar getting involved — prompting the man and his entourage to head to the Tilden Houses to ambush Shamar, according to the aunt.

“Shamar came upstairs to go in his apartment," Davis said through tears. "He takes the key and put it in the door. They was waiting for him. Shamar was at the door, trying to go inside . . . When they shot him, he was trying to run to the elevator and they shot him again in the back and he fell.”

Shamar’s mother, who had gone shopping nearby, heard the shots about 9:25 p.m. and came running upstairs with police only to find her son dead outside their doorway.

“She sees Shamar on the floor bleeding and when she runs to my nephew he already lost his life," Davis said.

The shooter bolted to a “crash pad” in the building, cops said, where one of his pals tossed the murder weapon out a window in a bid to keep police from finding it. But police recovered the weapon — and 25-year-old Tejion Lee was arrested for murder and weapons possession.

Cops found Lee holed up in the crash pad apartment with seven men and two women, authorities said. All the occupants were hauled in for questioning by police.

Lee was ordered held without bail by a Brooklyn Criminal Court judge after he was arraigned on murder charges Tuesday.

Shamar recently left Monroe College, after attending for a year, to look for work. He planned to return to college.

He started staying with his aunt, who has respiratory issues, in East Flatbush at the start of the coronavirus lockdown to look after her. Police said Shamar had no criminal record.

“He gets my groceries," Davis said. "He takes my garbage downstairs. He helps me. He do everything for me.”

“They don’t know what they do to me,” she said of the shooter.

The slain young man moved back in with his mother and sister at the Tilden Houses two weeks ago after taking a job at a liquor warehouse that kept him too busy to care for his aunt.

“Do you think I should go?” Shamar had asked her. She told him to take the job because he needed the money.

“He took his stuff and said, ‘Aunty Karen, I’ll call you,” Davis recalled of the last time the two were together.

“I can’t even sleep," Davis said. "Every minute I think about Shamar. I can’t live without him. I don’t know what I’m going to do.”
