Authorities in southeast Nebraska say a man set a house he owns on fire to evict his son from living there.

The Nebraska Fire Marshal's Office says Rex Peterson Sr. confessed to pouring gasoline Friday throughout the two-story house in Nebraska City. An arrest affidavit says the man didn't want his 29-year-old son living there any longer.

The son and his girlfriend were at home when the fire began. They both escaped without injury.

Peterson was charged Monday in Otoe County Court with first-degree arson. He faces up to 50 years in prison if convicted. He posted bail and has been released.

The affidavit doesn't say why Peterson wanted his son out of the house. His attorney declined to comment.
