An arson sign is posted where a mobile home once stood at Zumbro Ridge Estates.
The Rochester Fire Department said, no one was living in the home that was engulfed when firefighters arrived on scene around 3 a.m. Wednesday.
After an investigation involving the Rochester Fire Department, State Fire Marshal, and Olmsted County Sheriffs Office, this fire is now believed a case of arson. The fire caused about $10,000 in damage.
Investigators say the fire started in the living room area. A neighbor told the NewsCenter, he saw teenagers come in and out of the vacant home.
The fire department is asking that anyone with tips call the arson hotline. That number is 800-723-2020.
