The death of a Queens woman who was found face-up in bed by her mom two months ago has been ruled a homicide, authorities said Friday.

Victim Jennifer Richard, 26, suffered neck trauma consistent with strangulation, police sources told The Post, adding that the city’s medical examiner ruled her death a homicide.

Her body was discovered inside her Richmond Hill apartment on 115th Street — where she lived with her mom and brother — around 6:20 p.m. June 24. Her brother was in India at the time, neighbors said.

Richard’s mother saw her in bed after she got home from work, and without realizing the young woman was already dead, said to her, “What’s your problem? Why didn’t you call me today?” according to the daughter of a woman who lives on the second floor of the home.

When Richard did not respond and her mother realized something was horribly wrong, the mom ran upstairs to her neighbor for help.

“She just told my mother, ‘My daughter’s not responding!’ My mother went down to look and she realized she was dead,” said the woman, who declined to give her name.

“My mom said [Richard] was wearing panties … and had the sheets over her,” the woman said, adding that the victim’s mother “was shocked.”

Richard’s mom called police, and the young woman was pronounced dead at the scene.

The neighbor’s daughter said that whoever was responsible for Richard’s death “played it out very smartly.

“[Police] fingerprinted the entire house and didn’t find anything,” she said.

She called Richard “very nice” and a “happy girl” who was planning a trip to India.

Ricky Singh, 37, a friend of Richard, said he worked with the victim roughly two years ago at a tattoo supply company. Richard also worked as an administrator at a CityMD.

“She said she found a very good job and was very happy,” Singh said. “She wanted to achieve so much and go so high and be successful in life.”

“She was a good girl,” he said. “Always very helpful.”

Neighbors said the victim’s family has since moved out of the Queens home.

The building’s landlord, who did not want to give his name and said he was in India, said Friday of Richard’s death, “It’s very sad. It’s very sad.”

Richard’s Facebook page, which has been changed to say “Remembering,” described her as an “optimist,” “story teller,” “overthinker” and a “pacifist.”

No arrests have been made in the case.
