LOVELAND, Colo. (AP) — Family and neighbors say the man found shot to death along a street in northern Colorado was a cancer survivor who often took late-night walks through his quiet neighborhood.

They identified the man as 65-year-old William Connole, but police haven’t released his name.

He was found late Wednesday about two blocks from his home in normally safe Loveland. Police are looking into whether the man’s death is related to two other recent unsolved shootings nearby.

In one, a bicyclist was found dead along a rural road. In the other, a driver was shot in her neck on Interstate 25. She survived.

The incidents have raised alarm about a possible serial shooter in the area. Authorities have declined to comment on that and say it’s too early to know if the Loveland shooting is connected to the other two.
