Overview

• Ramsey County prosecutors filed two counts of second-degree murder and a second-degree assault charge against 52-year-old Lloyd Matthew McKenzie.
• The man in his 30s died during surgery Friday after being found with stab wounds in a hallway at the County Road D East apartment building, and the medical examiner ruled the death a homicide.
• Charging records allege McKenzie broke into the mother's apartment days earlier, kept her there without her phone or keys, assaulted her and used crack.
• Witnesses told police the stabbing occurred in the doorway when the daughter and relatives came to get the mother, and officers later recovered a bloodied serrated kitchen knife under a mattress.
• McKenzie told investigators he acted in self-defense after a gun was pointed at him, but officers reported finding no firearm.
