Overview
- Minneapolis police said Tuesday the 71-year-old man died at the hospital after the April 5 attack, and they have not released his name.
- Officers found him unresponsive near the 15th-floor elevators at 314 Hennepin Avenue with signs of severe head trauma noted in the criminal complaint.
- Investigators say video shows an argument before the suspect punched the man, and a building guard reported a long-running feud between the neighbors.
- Police arrested building resident Michael Joseph Walker, 61, who was initially charged with first- and third-degree assault and remains in custody.
- The Hennepin County Attorney’s Office is expected to add a homicide count, a move prosecutors can take when an assault victim later dies.
