Harlem woman stabbed to death in hallway ambush by ‘jealous’ ex-boyfriend ID’d as mother of four

A Harlem woman ruthlessly stabbed dozens of times and left to die in a vicious ambush by her ex-boyfriend was officially identified by police Tuesday as a mother of four.

Carmen Lopez, 47, was knifed about “50 times” – leaving her within inches of her life – around 4 a.m. Monday near the elevator on the third floor of her rental building on West 129th Street near St. Nicholas Terrace, cops and sources said. 

Her alleged assailant was her on-again, off-again beau who may have been fueled by jealousy, the sources said. The two were not together at the time of the slaying, the sources said. 

Building porter Lyron Middleton happened to be cleaning the staircase when he stumbled upon Lopez covered in blood and called 911, he said. 

Lopez was rushed to Mount Sinai Morningside hospital, where she succumbed to her grave injuries, cops said. 

Surveillance footage – which Middleton couldn’t bear to watch but only listened to the audio – captured the moment the attacker ambushed Lopez after apparently waiting on the steps for two hours, sources and the porter said.

“She was yelling out someone’s name as it was happening,” Middleton said of the footage. “They say, ‘Luis, Luis, Luis. Luis stop, Luis stop.’”

The alleged killer was taken into custody hours later, and was brought to Lincoln Medical Center for a 24-hour psychiatric hold, according to the sources. 

He was back at the 26th Precinct awaiting charges Tuesday afternoon, the sources said.

A building superintendent told reporters Monday that the victim had four kids, two who live with her and two who are older and live in New Jersey. 

“I don’t know how did this happen, because they are not a problem person, any one of them. They are nice [people], like our family,” the worker said.
