Six people, including four children, died in a house fire in northern Wisconsin on Tuesday, investigators said.

Firefighters were called to a “fully involved fire” at the multi-family residence around 6:30 a.m. in Pickerel, which is about an hour-and-a-half drive from Green Bay, the Langlade County Sheriff’s Office told Fox News.

Eight people were in the house when the fire started and two were able to escape, according to Langlade County Coroner Larry Shadlick.
