Kalamazoo, Jumada I 12, 1437, Feb 21, 2016, SPA -- A gunman who seemed to choose his victims at random opened fire outside an apartment complex, a car dealership and a restaurant in Michigan, killing at least six people during a rampage that lasted nearly seven hours, police said. Authorities could not say what motivated 45-year-old Jason Dalton, who has no criminal record, to target victims who had no apparent connection to him or to each other. "How do you go and tell the families of these victims that they weren't targeted for any reason other than they were there to be a target?" AP quoted Kalamazoo County Prosecutor Jeff Getting as saying Sunday during a news conference. Dalton was arrested early Sunday in downtown Kalamazoo following a massive manhunt. He was expected to be arraigned Monday on charges of murder and attempted murder. Kalamazoo County Undersheriff Paul Matyas described a terrifying series of attacks that began about 6 p.m. outside the Meadows apartment complex on the eastern edge of Kalamazoo County, where a woman was shot multiple times. She was expected to survive. A little more than four hours later and 15 miles away, a father and his 18-year-old son were fatally shot while looking at cars at the dealership. Fifteen minutes after that, five people were gunned down in the parking lot of a restaurant, Matyas said. A 14-year-old girl had earlier been reported among the fatalities, based on a pronouncement by medical officials. But police later said that she was hospitalized in serious condition. Authorities did not believe the shootings were targeted at specific people, describing them as "our worst-case scenario," Matyas said. "These are random murders," he said. Dalton was arrested without incident about 12:40 a.m. after a deputy spotted his vehicle driving through downtown Kalamazoo after he left a bar parking lot, authorities said. --SPA 19:51 LOCAL TIME 16:51 GMT www.spa.gov.sa/w
