UPPER WEST SIDE, Manhattan (PIX11) — Four people, including two young children, were found dead in an apartment on the Upper West Side in Manhattan Monday, according to authorities.

Police were called to the apartment on West 86th Street around 3 p.m. for a wellness check. When they arrived, police found the victims unresponsive with multiple stab wounds, authorities said.

Edison Lopez, 41, and Alexandra Witek, 40, had trauma to their neck, and 3-year-old Lucien Lopex and 1-year-old Calvin Lopez had trauma to their bodies, according to police. All were pronounced dead at the scene, authorities said.

Neighbors said Lopez was the super in the apartment building who had recently given his notice to take another job as a super in Westchester County. He and his family lived in the one-bedroom “super’s apartment.” The new job came with a three-bedroom apartment, according to his neighbors.

Police said there were no signs of forced entry, and they are not looking for any suspects. Investigators suspect the deaths were a murder-suicide. The investigation remains ongoing.
