A Lindenhurst woman killed by a hit-and-run driver was the third member of her family to die in a pedestrian crash in recent years, according to police.

The body of Pauline Aluska, 54, was found Monday on Montauk Highway, near South 13th Street, a block from where her brother, John Aluska, 61, also of Lindenhurst, was killed less than two years earlier, Suffolk police said.

Both siblings died after they were struck by hit-and-run drivers, whom authorities have not yet identified.

On Monday, their brother, Kenny Aluska, also of Lindenhurst, urged the drivers responsible for the deaths to surrender to the authorities.

“If you have a heart. If you have a soul, turn yourself in . . . ,” Kenny Aluska told reporters in an interview Monday.

This past Mother’s Day, Kenny Aluska’s wife, Diane Aluska, 55, was killed when a car struck her moments after she had pushed her 16-year-old daughter out of harm’s way. Diane Aluska and her daughter were walking on a sidewalk on Wellwood Avenue in the Village of Lindenhurst when police said a 2005 Toyota Corolla hit her and clipped her daughter, Jenna before crashing into the Lindenhurst Fire Department.

Diane Aluska was credited by police and her husband with saving Jenna’s life.

“I have no doubt that she saved her daughter’s life,” Det. Sgt. James Murphy said at the time of the May 14 crash.

The driver of that car, Ann Riolo, 80, also of Lindenhurst, was not charged, police said, and that investigation is continuing.

Kenny Aluska said words cannot describe the tragedy that his family has experienced. His love for his children, he said, is what keeps him going.

“I’m just trying to take care of my kids,” he said.

On Monday, at 12:20 a.m., Suffolk police received a 911 call. The caller told police that a woman’s body was on the side of Montauk Highway, near 13th Street. The woman, later identified as Pauline Aluska, was taken to Good Samaritan Hospital Medical Center in West Islip, where she was pronounced dead. Police did not know where Pauline Aluska was heading to or where she was coming from.

On Sept. 28, 2015, her brother, John Aluska, was found on Montauk Highway, just west of Venetian Promenade, about 1:20 a.m., police had said at the time. Police said he was struck by a vehicle traveling east that left the scene.

Pauline Aluska, according to her brother, was making plans to move to Florida.

“She was pretty cool. We used to go on the water all the time,” Kenny Aluska said. “We used to go on the boats; went out on the water, had a good time, you know, fishing, clamming, hanging out at the beach.”
