Accused NYC gunman Sundance Oliver’s 3 victims linked by shootings; ‘I feel sick, hurt,’ says slain teen’s mom

Bullets killed a 21-year-old man and a 17-year-old girl and wounded a 96-year-old man — three people cops say are forever linked by having been shot by ex-con Sundance Oliver.

It began at 9:30 a.m. Monday, when police say Oliver fired a bullet that punched through 96-year-old Sandy DeWalt’s right calf as he sat in his wheelchair waiting for a bus at Rochester and Bergen Aves. in Crown Heights, Brooklyn. The bullet that hit DeWalt missed the 21-year-old woman Oliver aimed at, said cops.

Five hours later, at 2:40 p.m., Oliver fatally shot Kevon “Biggz” Langston, 21, during a clash at the Alfred E. Smith Houses on the Lower East Side, said police. Langston was known for tooling around the Smith Houses on his bike.

Early Tuesday morning, about 10 hours after he shot Langston, Oliver shot and killed Keyaira Rattray-Brothers, 17, at an apartment in the Kingsborough Houses in Brooklyn, cops said.

“You hear about stuff like this all the time, but you never think it’s going to happen to your own flesh and blood,” said the teen’s heartbroken mother, Tasha Rattray.

The teen lived in Bedford-Stuyvesant, about a mile away from the Kingsborough Houses in Crown Heights, police sources said. Rattray had never heard Oliver’s name before she was told he had shot her daughter in the chest at 12:12 a.m. Tuesday.

“(I’m) destroyed, depleted, confused,” Rattray told the Daily News. “I just spoke to Keyaira at 6:30 p.m. yesterday afternoon. She told me she’ll be home soon.”

Oliver surrendered to authorities at the 77th Precinct stationhouse at about 7 a.m. Tuesday. A motive for the back-to-back killings was not immediately disclosed. Criminal charges were pending.

“I don’t know that man but I hope he gets everything that’s coming to him, because it’s not right,” Rattray said. “He took my daughter and somebody’s son!”

Keyaira, an Independence High School junior, told her mom that she was hanging out with friends at the Kingsborough Houses following a “tattoo party” where someone put a butterfly with the word “breathe” on her skin.

“(She was) a beautiful soul, kind to everybody and a friend with everybody,” longtime friend Rell Reign said. Keyaira and Reign had hung out on Monday before the teen went to the tattoo party.

“I feel sick, hurt. I’ve been crying all morning. I’m in shock,” said Reign.

Keyaira loved to dance, but her true gift was her voice, her mother said.

“Her voice was so beautiful it would make you cry,” she said. “The angels in heaven rejoiced when my baby sang!”

Langston, the 21-year-old, was a trickster who enjoyed performing stunts on his two-wheeler, said friends who had left a memorial outside the Smith Houses building where he was shot.

He lived for popping wheelies, said his buddies, who shared a video on Instagram of him riding three blocks on one wheel.

The video ends with the words “Ride in Peace.”

“Biggz” had a signature move where he popped a wheelie, leans back on the bike, his foot dragging on the asphalt and “one hand pointing towards someone behind him,” his friend Ibrahim Bah told the News.

“Bikes, I’m telling you! That’s how I met him,” Bah said. “I spoke to him Saturday. We were laughing. It was a funny video that we were watching.”

Langston grew up in the Smith Houses, where Oliver’s foster mother lived. When he died, he lived on the Upper West Side. It wasn’t clear why he was visiting the Smith Houses Monday.

“He was always outside. He always liked to play fight,” one longtime friend, who would only identify herself as Keke, said.

Langston, had his own run-ins with the law, with two arrests for robbery, plus one for hate crime assault and one for grand larceny, police said.

His family, however, was shell-shocked at his murder.

“That was my brother,” said a man who wouldn’t identify himself. “He never had no problems with anybody. We can’t believe this.”

The back-to-back murders rattled DeWalt, a retired truck driver, who realized Tuesday that at age 96 he was lucky to have avoided being the first victim of a homicidal hat trick.

“I heard a gun go ‘Pow!’” the man recalled. ”I felt it and my leg jumped. I looked down and it was bleeding.

“I guess God wasn’t ready for me yet,” he said. “I’m still here.”
