In a tragic turn of events on the evening of September 20, 2026, 34-year-old Matthew Leib lost his life in his Albuquerque, New Mexico, home. The man accused of this violent act was his own father, 64-year-old Mark Leib. The incident unfolded at their residence on Sabre Court NW, where Matthew was present with his girlfriend and another friend. The evening took a dark turn when Mark Leib returned home from work, reportedly in an agitated state and making threats to kill someone.
According to witness statements, Matthew's girlfriend attempted to de-escalate the situation by persuading Mark to go into his bedroom. However, he soon emerged armed with a shotgun. A physical altercation ensued between Mark and his son's girlfriend, during which he allegedly punched her and threatened her life. Fearing for their safety, the girlfriend and the friend fled the house. When they returned a short time later to check on Matthew, they were met by Mark, who chillingly announced that he had killed his son. Inside, Matthew was found in the hallway with multiple gunshot wounds to his chest.
Following the incident, Mark Leib was arrested by the Albuquerque Police Department. He reportedly made a confession during a 911 call, stating, "I killed my fucking son." He is facing an open count of murder, two counts of aggravated assault with a deadly weapon, and aggravated battery with a deadly weapon. The case against Mark Leib is now proceeding through the legal system. This deeply distressing event highlights a fatal domestic dispute that ended in a son's death at the hands of his father, leaving a family shattered and a community in shock.
