Police said a suspected killer of seven people in Grand Rapids, a southwest Michigan city, killed himself late Thursday night after an 8-hour manhunt and standoff, the Grand Rapids Press reported.
Grand Rapids Police Chief Kevin Belk told a news conference that the suspect, identified as Rodrick Dantzler, 34, was dead at the scene, and the two hostages remained safe, Xinhua reported.
Belk said Dantzler released a 53-year-old woman but still held two others before he fired a shot into his own head.
Dozens of police officers cordoned off a city neighborhood at about 8 p.m. local time (2400 GMT) after seven people, including two children, were fatally shot in related shootings at two homes in the city Thursday afternoon.
Four people were found dead in a Grand Rapids home and three others were found in another home, and the killing rampage appeared to stem from domestic issues, police said.
"This is a rare occurrence anywhere," said Grand Rapids Mayor George Heartwell. "A homicide like this is exceedingly rare. It's an awful situation."
Police officers were reportedly involved in a chase at around 7 p.m. local time (2300 GMT), through downtown Grand Rapids to northbound U.S. 131 roadway and then eastbound I-96.
During the chase, a pedestrian was struck by Dantzler's car and he also shot two people, but they did not suffer life-threatening injuries, according to the police.
Shots were also fired from inside the apartment near the Plainfield Avenue and I-96 where the hostages were taken.
