A Douglas County judge ruled Friday that prosecutors could present testimony at an upcoming trial about events leading up to a June 2008 Lawrence mobile home fire.

Trevor A. Toussaint, 44, Lawrence, faces arson and burglary charges and is accused of setting fire to the mobile home of his ex-girlfriend, Kimberly Berry. His trial is set to begin Monday in Douglas County District Court.

Judge Paula Martin ruled that prosecutors could present testimony from Berry about five previous times when she said Toussaint entered her home without permission.

Prosecutors accuse Toussaint of breaking into her mobile home on June 10, 2008, in the Harper Woods mobile home park, 2200 Harper St. Fire investigators have ruled the blaze was set intentionally after gasoline was poured onto Berry’s bed and in the hallway, and then ignited.

The defense has disputed that Toussaint was identified as the person who broke into the trailer.
