WAUSAU, Wis (WSAU) Prosecutors say a mobile home fire at Lazy Acres earlier this week was intentionally set. They’ve charged Keith Rosenow with three counts of reckless endangerment and one count of unsafe burning. He appeared in Marathon County court yesterday.

A police report says Rosenow had a long-running dispute with the management at the trailer park.

Investigators say they still haven’t determined exactly how the fire was set. Several members of the fire department say they personally know the suspect, and want an outside investigator called in to avoid a conflict of interest.
