MURDER SUICIDE IN QUEENS!

A 76-year-old Queens barber slashed his wife's throat with a butcher knife Sunday, then turned the knife on himself as their developmentally disabled son watched in horror, cops said.

The bloody murder-suicide occurred about 7:35 p.m. in the Ozone Park apartment that the killer, Eusebio Salazar, shared with Geraldina Salazar, 51, and their grown son, who was born with Down syndrome.

"My mom! My mom!" cried the son, who ran downstairs to get deli owner Darrio Urquijo, 50.

Urquijo said he found the husband and wife on the floor of their bedroom, a brown-handled knife sticking out of the man's chest.

"I go with the kid and I see the guy on the floor, the wife, too, and he has a knife in his chest," Urquijo said. "There was a lot of blood on his hands."

Geraldina Salazar was still breathing when cops found her with several stab wounds to the neck and torso. She died at Jamaica Hospital.

The couple owned the Selvin's Unisex Hair Salon downstairs from their apartment on Jamaica Ave.

Neighbors said Eusebio Salazar suffered a stroke recently and had been depressed.

"They were wonderful people," neighbor Sandra Liciaga said. "They looked happy. That's why I'm so shocked."

She said the couple showered affection on their son, who is in his 20s. "They lived for that boy. Their son was their life," Liciaga said.

Liciaga said she saw the son making a slashing motion with his hands across his throat as he tried to explain to cops what he saw his father do to his mother.

"I just feel bad for that boy," said Liciaga. "He doesn't know any better."
