Saginaw PD: Homeowner fatally shoots man knocking on door

Investigators say a 21-year-old Saginaw man had gone to three or four homes, knocking on the front doors. One homeowner answered the door and told him to go away. Police say the homeowner shot him after he rushed toward the homeowner. But the man's mother says her son suffered from a medical condition and had likely wandered out of his home and needed help.
