EL PASO, Texas -- A man is found dead in his central El Paso apartment and police tell KFOX his ex-girlfriend may be responsible. She spoke exclusively to KFOX.

"I'm guilty, yeah. I stabbed him three times but I didn't kill him," those were the words of 18-year-old Priscilla Gonzalez as she was handcuffed and was being escorted to jail from police headquarters.

Police said Gonzalez stabbed her ex-boyfriend 22-year-old Abraham Ontiveros, killing him early Thursday morning.

According to police, Gonzalez showed up at the apartments on 1616 Stanton, where Ontiveros lived. She found him with friends, including another woman. After everyone left, she allegedly came back to the apartment and and stabbed Ontiveros to death.

Savanna Hayes knew the victim. She lives next door to where the stabbing happened.

"It feels weird because I did hang out with him when I was a freshman. He was really kind. Sometimes he wasn't there but he was really nice," Hays said. Detectives didn't find the murder weapon at Ontiveros' apartment so they searched Gonzalez 's apartment a few blocks away on Yendell hoping to find any evidence linking her to the killing .

Meanwhile, those who knew Ontiveros said their thoughts are with his family. "He did nothing wrong to anyone, ever, so I have no idea why they would try to do that. He's never done anything. Now I like feel bad for his mom, that she has to go through that for him," Hayes said.

Detectives arrested and booked Gonzalez into the El Paso County Detention Facility on one count of murder with a $250,000 bond.
