The shootings some 9 miles (14.5 kilometers) apart in northwestern Wisconsin left a total of five people dead, including the suspect, and two others wounded, authorities said.

Authorities found the shooter and another person dead while responding to a 911 call in Lake Hallie in about 10:30 p.m. Sunday, Sheriff James Kowalczyk told WQOW-TV. Authorities said the dead were a man and a woman, but Kowalczyk didn't say which one was the shooter or how authorities were able to determine who the shooter was.

Two other adults at the home in Lake Hallie were rushed to the hospital with gunshot wounds. There was no immediate word on their conditions.

Authorities looking to notify the shooter's relatives then went to a home in the Town of Lafayette around 2:30 a.m. Monday and discovered three more bodies, Kowalczyk said.

"We went to the door, received no answer, attempted to make a call, again no answer. We finally forced our way in and found three other victims of a homicide," Kowalczyk said.

The dead there were a man, a woman and a boy.

The names of the victims and the shooter have not been released. Kowalczyk told WQOW that authorities were still trying to determine a motive. The sheriff didn't immediately return a phone message left by The Associated Press.

Hannah Larson, who lived in the same four-unit complex in Lafayette, told the Minneapolis Star Tribune an 8-year-old boy lived there along with his father and grandmother. Larson said the 8-year-old had sometimes played with her 7-year-old brother.

Lafayette Chairman Dave Staber said the shooting in his town has rocked the normally quiet, bedroom community of 6,000.

"We're seldom in the news, which is just the way we like it. My heart goes out to the residents affected by this," Staber said.
