UWS murder-suicide family identified as building super, wife and sons

The Upper West Side family found dead Monday afternoon in what police believe was a murder-suicide have been identified as the apartment building’s superintendent, his wife and young sons, law enforcement sources said — noting that one of the boy’s bodies was so bloody, he was initially misidentified as a girl.

Edison Lopez, 41, is believed to have stabbed his wife, 40-year-old Alexandra Witek, and their two young sons before taking his own life, police insiders told The Post.

The 3- and 1-year-old boys’ bodies in particular were in such terrible condition when they were found Monday afternoon that investigators initially misidentified them as a boy and a girl, they added.

Prior to the killings, the family had no emergency call history indicating any domestic strife, the sources said.

Lopez, Witek and their sons were found in their home on West 86th Street near Riverside Drive around 3 p.m. Monday, when Lopez’s father called Witek’s younger brother after being unable to reach the family since Sunday, the sources continued.

The brother, who is the superintendent of a nearby building, alerted authorities when the pair drilled out the lock of the apartment and saw blood inside.

First responders initially discovered the two children in the living room with several stab wounds and two knives nearby, the sources said.

Witek’s body was found in the hallway with a deep cut to her neck, they continued, while Lopez was found lying on a bed in a bedroom.

The father of two also had a stab wound to his neck and there was a knife next to him.

All four individuals were pronounced dead at the scene.

The apartment door was locked from the inside, police said.

The family had no known criminal history, and there is no record of police being called to their home in the past, sources said.
