Four people killed in apparent murder-suicide in De Pere

DE PERE, Wis. (AP) -- A man killed his wife and two children before killing himself in the Green Bay suburb of De Pere, police said Friday.

Police Chief Derek Beiderwieden said a man called police from inside the house about 3 p.m. to report that he had just killed three people and was about to kill himself.

The phone line went silent, and others at the police station then heard a loud "pop," Beiderwieden told reporters.

Officers arrived at the single-story home a short time later and found four victims -- two adults and two children -- shot to death in a bedroom. Authorities recovered a firearm believed used in the apparent murder-suicide, the chief said.

Investigators had not determined a motive but were gathering evidence Friday night. The names of the victims were not released.

It's a "very, very tragic day for De Pere," Beiderwieden said. He said he believes the community is safe and it apparently was an isolated incident

Dan Angell, who lives across the street, said the family seemed like a normal family

"I would have never guessed that any of that would have happened," Angell said.

A police truck was outside the ranch-style home with an attached garage Friday evening. Beiderwieden said he does not believe police had been called to the house for any previous trouble.
