A 51-year-old man was arrested on suspicion of murder after DNA confirmed a decomposed leg found in a Southern California field belonged to a missing teenage girl from Riverside County.

Abraham Feinbloom, a resident of Salton City, was apprehended on Friday as authorities continue searching for the remains of 17-year-old T’Neya “TT” Tovar.

As deputies and FBI agents arrived with a search warrant at his Harlequin Court home around 7:30 a.m., Feinbloom allegedly jumped a fence in an apparent attempt to flee but was quickly captured, KESQ-TV reported.

Feinbloom was arrested and booked into Imperial County Jail on charges of murder and resisting a peace officer. He is being held without bail.

Tovar, a resident of Hemet who had been described as “headstrong” and “full of energy,” was last heard from on Dec. 1, when she called her mother to say she was heading to Palm Springs, promising to return home within two weeks.

Her mother Charro Tovar filed a missing person report. She told authorities that she later learned T’Neya was traveling to meet Feinbloom, according to KESQ-TV.

Friends told Charro Tovar they had seen T’Neya with Feinbloom in October at the 7th Street Metro transit station in Los Angeles, suggesting their contact may have begun months before she vanished, the local TV station reported.

In the weeks that followed, her parents repeatedly drove roughly 70 miles from their Riverside County home to a boarded-up pink home on Harlequin Court in Salton City, where T’Neya’s phone last pinged.

They say deputies conducted four welfare checks but never forced entry and suggested the teen might be a runaway.

“If they had acted sooner, maybe my child could have been saved,” Charro Tovar said in an interview with KESQ-TV.

Neighbors reported hearing drums, seeing bright lights and hearing occasional screams coming from the house, and one family nicknamed Feinbloom “the scary man in the scary house.”

On Dec. 21, deputies responded to a reported sighting of human remains in a field in the Vista Del Mar section of Salton City.

Law enforcement officials recovered a decomposed human leg, but could not determine the sex, age or race of the person to whom it belonged.

DNA testing by forensic pathologists later confirmed that the leg belonged to T’Neya. The official confirmation came last week — more than two months after the original DNA sample was taken from the family on Dec. 6.

On Dec. 23 — two days after the leg was discovered — neighbors said Feinbloom began installing multiple security cameras around his boarded-up pink home, which is surrounded by a pink cinder-block wall.

Charro said she is frustrated investigators have not kept her informed.

“They haven’t told me anything,” the mother told The Post. “They haven’t even told me that they arrested him in connection to my daughter’s murder.” She added: “I found it through news reports… and through social media… Not an email, not a phone call.”

Public records list Feinbloom as a musician who had lived at the home for years. County property records show the deed remained in the name of his deceased parents.

The investigation remains active, with the FBI offering a $10,000 reward for information related to the case.

The family and law enforcement officials were not immediately available for The Post’s request for comment.
