Former boyfriend arrested for stabbing Harlem mother nearly 50 times, leading to her tragic death.

In a tragic incident that has shocked the community, Luis Marquez, a 31-year-old man, has been arrested and charged with the murder of Carmen Yadira Lopez, a 47-year-old mother of four. Lopez was fatally stabbed in the early hours of November 10, 2025, in the hallway of her Harlem apartment building. Authorities reported that Marquez has been in a tumultuous and on-and-off relationship with Lopez, during which they experienced significant conflict.

According to police reports, Marquez consumed alcohol prior to the incident and reportedly felt disrespected by Lopez’s lack of reciprocation toward his feelings. Witnesses characterized the crime as particularly brutal, noting that Marquez allegedly waited for over two hours in a stairwell before ambushing Lopez as she exited the elevator on her floor around 4:25 a.m. She suffered nearly 50 stab wounds during the attack, which neighbors heard, as Lopez can be heard pleading for her life in distressing screams.

The horrific events unfolded in the vicinity of West 129th Street and St. Nicholas Terrace, where residents have been left reeling. Building porter Lyron Middleton discovered Lopez’s body shortly after the assault, reporting a scene marked by bloodshed and chaos. Eyewitness accounts from other residents indicate that despite not intervening at the moment, many were struck by the urgent sounds of Lopez’s pleas for help.

Emergency medical services transported Lopez to Mount Sinai Morningside Hospital, where she succumbed to her injuries shortly after arrival. The local community mourns the loss, with Lopez being remembered as a devoted mother whose family relied on her. She lived with her mother in the apartment, having resided in the building for decades. Two of her children, ages 7 and 14, still lived at home, while her two adult sons reside elsewhere.

Marquez, who has no prior criminal history, is currently in police custody after being apprehended later that same day. After undergoing a brief hospitalization, he was transferred back to the 26th Precinct for questioning. His arraignment in Manhattan Criminal Court is anticipated soon, as law enforcement continues to investigate the circumstances surrounding this shocking murder.

This incident highlights the tragic realities faced by many in dysfunctional relationships, raising broader questions about domestic violence and community safety. Eyewitnesses and residents expressed their heartbreak over the situation, lamenting that the relationship history between Lopez and Marquez had not previously alerted authorities to the dangers that ultimately resulted in such a devastating outcome.

As the investigation unfolds, the focus remains on ensuring justice for Lopez and addressing the underlying issues of domestic violence that persist in many neighborhoods. The community stands united in remembrance and support for Lopez’s family during this profoundly difficult time.
