GRAND RAPIDS (AP) -- Grand Rapids police say a 34-year-old ex-con, whose criminal past barred him from owning firearms, used a stolen .40-caliber handgun to kill seven people and wound two others before taking his own life.
Police Capt. Jeffrey Hertel says investigators are trying to figure out what motivated Rodrick Dantzler to kill two ex-girlfriends, his 12-year-old daughter, and four other people on Thursday.
Hertel says the gun was stolen from a home in western Michigan's Kent County, which includes Grand Rapids.
The Grand Rapids Press says the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives is tracing the gun's history.
Dantzler has a criminal record dating back to a 1992 juvenile arrest for burglary, and his mother and at least three other women have sought protective orders against him.
