Authorities in Florida say an 11-year-old girl and her 15-year-old boyfriend tried to set the girl's mother on fire while she slept.

CLEARWATER, Fla.  Police say an 11-year-old girl plotted with her teenage boyfriend to kill the girl's mother by setting fire to her bedroom as the woman slept Tuesday. Samantha Broadhead and Jack Ault, 15, were arrested after they allegedly poured gasoline on Nancy Broadhead's bedroom floor and bed, then ignited it. They then took the mother's 2007 Ford Focus and fled the scene. Clearwater Police spokeswoman Beth Watts said it appears an ongoing problem in the home escalated Tuesday. "As for a motive or how this all came about, apparently it's your typical teenaged angst that probably has been going on for some time and it escalated yesterday when the mother confronted the daughter about stealing a few of her cigarettes," Watts said. Nancy Broadhead was awakened by a smoke alarm in the home and was able to get out. She sustained serious burns and smoke inhalation. Broadhead was taken to Morton Plant Hospital and has since been transported to Tampa General where she was admitted to the burn unit. Officials say her injuries are serious, but not life threatening. She is now listed in fair condition. Samantha Broadhead returned to the scene and agreed to go to police headquarters for questioning. Jack Ault was located and taken into custody at a friend's house. Detectives charged both juveniles with attempted murder and arson resulting in serious injury. Officials say Ault also faces a grand theft charge for stealing the victim's car, which was recovered in a church parking lot in Clearwater. Ault is being held at the Pinellas County Juvenile Assessment Center where he will undergo a psychiatric assessment.
