BURLINGTON (AP) - A Burlington woman who police say head-butted her daughter after they argued about chores has been charged with child endangerment.

Police say 34-year-old Shelly Lynn Worley sent her daughter to her room on Aug. 5 after they argued. They say Worley sat on top of the 14-year-old girl and pinned her to the bed. They say Worley grabbed her daughter's head and head-butted her twice.

Police say she later returned and threw an inflatable mattress on top of her daughter, sat on top of it and punched it repeatedly.

Worley was first charged with serious assault but the charge was recently amended after it was learned the girl suffered a bruised head and a sprained neck.
