Police: Florida man set woman's house on fire after dispute

PORT ST. LUCIE, Fla. – A Florida man has been arrested on suspicion he set a woman’s house on fire after a dispute.

The Port St. Lucie Police Department says 30-year-old Richard Caldwell was arrested Saturday and charged with arson and burglary.

The police said in a news release that Caldwell was involved in a dispute with the victim at a bar before she left with friends to go home.

The woman found Caldwell inside her house, asked him to leave, and he said “you’re going to regret this,” while holding a bottle with lighter fluid.

The victim left and returned to find her home engulfed in flames.

Caldwell returned, and a K-9 trained dog detected fire accelerants on his shoes and in his vehicle.
