怀特说，早上6点50分，第三名受害者是一名40多岁的女性，她被发现身中多枪，也在城市的西边，已经死亡。

怀特说，上午7点10分，第四名受害者是一名80岁的男子，他发现嫌疑人向车窗内窥视，于是与他对峙。

“当他告诉他离开车辆时，他转身向他开枪，打了他一次，”怀特说，并补充说受害者的手臂中弹。

警方说，周日晚上，这位80多岁的受害者在医院情况稳定。

受害者的姓名没有立即公布。

怀特说，嫌疑人没有抢劫或试图抢劫任何受害者。

怀特说，利用技术，调查人员能够快速分析每个犯罪现场的弹壳，并确定在所有四起枪击事件中使用了同一把枪。

“我们已经调动了我们所有的技术、人员、情报和社区资产来调查这些事件。我们目前正在搜索逮捕嫌疑人，”怀特说，并补充说，执法直升机也在全城搜索。

怀特说:“对于这些受害者的家人和朋友，我们将继续努力，将这名嫌疑人绳之以法。”。

底特律市长迈克·达根恳求公众帮助抓捕嫌犯。他要求人们研究发布的持枪危险罪犯的监控照片，如果他们看到他，请与警方联系。他说，任何与嫌疑人接触的人都不应该试图接近他。

他说，可能发生的最重要的事情是，在嫌疑人再次出现并实施袭击之前，认识嫌疑人或与嫌疑人有关系的人立即向执法部门举报。

“这个部门里没有人希望与这个人发生暴力冲突，”达根说。“这对我们的警官不安全，对肇事者不安全，对该地区的平民也不安全。”

Detroit on edge after gunman targets 4 random victims, killing 3

The city of Detroit was on edge after police said a single gunman randomlyshot four victims, three fatally, in 2 hours and 25 minutes Sunday morning.

The sole survivor of the killing rampage, an 80-year-old man, described being shot after spotting the suspect looking into cars and confronting him, police said.

An all-hands-on-deck search 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 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 to be the gunman. During a news 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 jacket with a hood.

"Evidence suggests a single suspect," White said. "At this time, we believe this to be a random act. There does not appear to be any relation 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 affiliateWXYZ.

The shooting began at 4:45 a.m. when a 40-year-old woman was discovered shot multiple times in a neighborhood on the west side of Detroit, the chief said. Police said the woman died from her injuries.

While officers were investigating the shooting, a witness walked up 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.

At 6:50 a.m., the third victim, a woman in her 40s, was found shot multiple times, also on the west side of the city, and died, White said.

And at 7:10 a.m., the fourth victim, an 80-year-old man, was shot after he spotted the suspect peering into the windows of vehicles and confronted him, White said.

"When he told him to get away from the vehicles, he turned and fired at him, striking him once," said White, adding that the victim was shot in the arm.

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 gun 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 were also scouring the city.

"To the families and friends of these victims, we will continue to work to get this suspect into custody," White said.

Detroit Mayor Mike Duggan pleaded for the public's help in catching the suspect. He asked people to study the surveillance photo released of the armed-and-dangerous perpetrator and to contact police if they see him. He said anyone who comes in contact with the suspect should not attempt to approach him.

He said the most important thing that can happen is that someone who knows the suspect or has a relationship with him comes forward to law enforcement immediately before he surfaces and strikes again.

"Nobody in this department wants a violent confrontation with this individual," Duggan said. "It's not safe for our officers, it's not safe for the perpetrator, it's not safe for civilians in the area."
