57-year-old Martha Dreher is a babysitter in Austin, Texas. She's been watching two girls, and apparently they were, quote, "very disrespectful." So . . . when the family was out earlier this month, she broke into the house and SET IT ON FIRE. A security camera caught her breaking into the house . . . then leaving about 20 minutes later. One of the family members eventually got home and saw the smoke. No one was hurt in the fire but there was a lot of damage. Now Martha's been arrested for arson, but she's pleaded not guilty and says she didn't start the fire.
