Police say a suspect is in custody hours after they found a woman engulfed in flames at a Boynton Beach convenience store. Boynton Beach police spokeswoman Stephanie Slater says a man doused a 40-year-old woman with gasoline and set her on fire early Monday. Two officers responding to a 911 call put out the flames and administered first aid. Police say she was taken to Delray Medical Center where she is being treated in the trauma center. Witnesses told police the suspect fled on foot. They tracked him with a K-9 unit and the Palm Beach County Sheriff's helicopter. Fifty-nine-year-old Roosevelt Monesir was taken into custody and then transferred to a hospital for burn treatment. Authorities have not released the woman's name or said why she was set on fire.
