Accused killer admits horrific sex assault-slay of girlfriend

An accused killer described in horrifying detail strangling his girlfriend and then sexually assaulting her in her Brooklyn home, law enforcement sources revealed.

Dylan Diaz, 26, was arrested Friday for the murder of his 18-year-old girlfriend, Damaris Maravilla (photo), who was found lying faceup on her bed on W. Sixth St. near Avenue O in Bensonhurst. Prosecutors say Diaz strangled her, sexually assaulted her then snapped her neck.

“I just didn’t care. I continued to strangle her, and I knew she was lifeless,” Diaz spilled to the police after his arrest, according to the law enforcement sources.

He then sexually assaulted Maravilla before snapping her neck, Diaz allegedly told cops.

“I kissed her body, and I told her go with God,” he said of the aftermath of the murder and sexual assault, according to the sources. “I wanted to make sure her mouth was closed. I closed her eyes, kissed her forehead, put her arms on her body and I snapped her neck.”

“My hands were bloody,” he added, the sources said. “I washed my hands ... and went to the store.”

The couple, who had a young child together, dated for more than a year and lived on the same block. The attack began after Maravilla spoke with another man on the phone, enraging Diaz, he told cops, according to the sources.

“This n—-a is soft, and he’s not going to do anything,” Maravilla, speaking of Diaz, told the man on the phone, Diaz told cops.

Diaz and the victim fought, then had “makeup sex,” Diaz said.

But afterward Maravilla and Diaz argued again, sending him into a murderous rage, the source said Diaz told cops.

It wasn’t the first domestic incident between the two. Cops were called at least four times when Diaz and Maravilla had blowout arguments over custody of their child, police sources said.

By Monday, locals had set up a makeshift memorial for the killed teen, with candles and flowers on the steps in front of Diaz’s home, where he allegedly killed Maravilla.

Neighbors recalled Diaz often acting erratically on the block.

His conduct was so unhinged that a nearby bodega worker, Wadah Ahmed, wanted to quit his job out of fear for his safety — even though he’s only worked there for a few weeks.

“That guy scared me every day, I swear to God,” Ahmed said. “I hated this job, I wanted to find another job because of him,” Ahmed said.

Diaz would come to the store every day and mumble to himself and pace around the store as he waited for his order to be prepped, often stealing lighters as he waited, workers recalled.

A teen worker at the bodega recalled how Diaz and Maravilla would fight inside the store when Diaz would try to repeatedly change his sandwich order.

“His girlfriend would say, ‘Stop, that’s it, enough.’ And he’d yell to his girlfriend,” the worker recalled, adding that the fights sometimes spilled out into the street and stopped traffic.

“The lady, she’s so nice,” the worker added. “Every time, I got problems with him only. And the girl would talk to him and say, ‘That’s it, enough.’”

At another neighborhood bodega, workers collected money in a can with Maravilla’s photo next to it, saying her sister had brought it to the store.

“She’s a good lady,” said employee Jaman Kamrugg, 50, recalling that Maravilla would come in with her baby in a stroller. “Always said hello.”

Kamrugg saw the family shortly after the murder. “They crying. The whole family is upset,” he said.
