NYPD detectives are probing the mother’s role in the death of an autistic man found in his family’s Queens home Wednesday, with his neck and wrists slit after she leapt from the Van Wyck Expressway, according to a police source.

Bryan Wong’s father found his son’s lifeless body on a pullout couch inside the living room of their single-family home on 59th St. near Laurel Hill Blvd. in Woodside around 9 a.m., the police source said.

Wednesday was Wong’s 25th birthday, cops were told.

The victim, who is believed to be non-verbal, had cuts on both wrists and the left side of his neck, the source said.

Investigators recovered a knife from the living room where Wong’s body was found, in addition to two more knives in the apartment’s bathroom.

“I saw the police come, but they didn’t take anybody out,” said neighbor Dani Ramirez, 21. “The mother and son were always together. He was nonverbal and autistic. I never saw any fight or trouble or anything.”

Around 4 a.m. in Flushing, the victim’s 62-year-old mother was found injured lying on Harper St. below the Van Wyck Expressway overpass, cops said.

She was taken to New York-Presbyterian Queens Hospital suffering fractures to her pelvis and femur, and is listed in critical but stable condition.

A motorist later told police he spotted the woman standing near a grey Hyundai on the northbound side of the highway as he drove by, the source said.

The autistic man’s death has not officially been ruled a homicide, but a police source said investigators found a suicide note written by his mother, who is suspected in his death.

The city’s Medical Examiner will determine how the man died.

Multiple neighbors told the Daily News that Wong was severely disabled and that his mother served as his round-the-clock caretaker.

“I would see the mother with her son, very tired and very stressed out,” said Patricia Guevara, who lives down the street. “He wasn’t able to speak. He was only able to make grunting noises. She hardly took him out of the house. It’s terribly sad.”

The victim and his family immigrated from Hong Kong, according to a home health aide his grandmother, who lives in a first-floor apartment below Wong.

“He would come, knock on the door to say good morning. His grandmother loved him,” said the aide.

“The grandmother doesn’t know,” she added. “I didn’t tell her.”

The aide described Wong’s mother as “a good mother who took her son to the park.”

Wong’s father shared a birthday with his son, turning 62 on Wednesday, according to police.
