St. Paul police shot and killed a man after a chase on the city's East Side. Police say 25-year-old Mitchell Moua was wanted on aggravated assault, false imprisonment and gun charges. Authorities were tipped off about his location yesterday and confronted Moua, who fled in a vehicle after pointing a gun at his own head. Moua's vehicle crashed into a semi and a van that had pulled over to allow police to pass. St. Paul police spokesman Tom Walsh says officers shot Moua after he opened fire on them.
