Three houses caught fire Thursday morning in Highland Park.
The fire started at a house on Portage Street just east of Hamilton Avenue. The flames spread to the houses on either side of it.
A man does live in the middle house and firefighters are looking for him. They aren't sure if he was at home.
No one was home in one other house and the other one is vacant.
A neighbor Local 4 spoke with said the fire started just after 10 a.m. with a loud blast.
"The middle house blew up ... there was smoke everywhere," the neighbor said.
She also said she was good friends with a man who lived in the middle house and was hoping he got out OK.
