The lone survivor of the killing, an 80-year-old man, described being shot after spotting the suspect looking into cars and confronting him, police said. A full-scale investigation involving multiple law enforcement agencies — including the FBI, the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Department of Homeland Security — was underway Sunday afternoon after police determined that the same gun was used in all four shootings, authorities said. Detroit Police Chief James White released a surveillance photo of a man they believe is the gunman. During a press conference Sunday afternoon, White described the suspect as a black man in his mid-20s to early 30s, wearing all black, including a black Carhartt hooded jacket.

There does not appear to be any connection between any of the crimes.” He said one of the victims was shot while waiting for a bus and another was shot while out walking a dog. Three of the four victims were fatally shot, police told Detroit ABC affiliate WXYZ. The shooting began at 4:45 a.m. when a 40-year-old woman was discovered shot multiple times in a neighborhood on Detroit’s west side, the chief said. Police said the woman died from her injuries. While officers were investigating the shooting, a witness went and informed them of another victim nearby, White said. Police found a 28-year-old man who had also been shot multiple times, the chief said. He also died from his injuries.

The octogenarian victim was in stable condition at a hospital Sunday night, police said. The names of the victims were not immediately released. White said the suspect did not rob or attempt to rob any of the victims. Using technology, investigators were able to quickly analyze shell casings from each of the crime scenes and determine that the same weapon was used in all four shootings, White said. “We have mobilized all of our technology, our personnel, our intelligence and our community assets to investigate these incidents. We are currently searching to apprehend the suspect,” White said, adding that law enforcement helicopters are scanning also the city. “To the families and friends of these victims, we will continue to work to bring this suspect into custody,” White said. Detroit Mayor Mike Duggan asked for the public’s help in apprehending the suspect. He asked people to study the surveillance photo released of the armed and dangerous assailant and contact police if they see him. He said anyone who comes into contact with the suspect should not attempt to approach him. He said the most important thing that can happen is for someone who knows or is related to the suspect to come forward to law enforcement immediately before he surfaces and strikes again. “Nobody in this department wants a violent confrontation with this person,” Dugan said. “It’s not safe for our officers, it’s not safe for the offender, it’s not safe for the citizens in the area.”
