Kent County Circuit Court records show 34-year-old Rodrick Shonte Dantzler was charged as a juvenile in 1992 with breaking and entering and car theft. His mother was among four women who sought protective orders against him in the mid- to late 1990s.
He spent three years in prison after shooting at people in a car in 2000.
On Thursday, police say he fatally shot two former girlfriends and five members of their families, including his own daughter. He also wounded another ex-girlfriend and a male motorist.
Dantzler later killed himself in a home where he held hostages.
