( Liberty Twp ) - A 16-year-old boy is in the Butler County Juvenile Detention Center accused of trying to burn down his parents' house with them inside.

Investigators say they were called to a house on Tarragon Ct, just off Hamilton-Mason Road around 11:30pm Wednesday for a fire. First responders say 50-year-old Perry Simon was outside the house after having jumped from a second story window. His wife, 56-year-old Sharon Simon was rescued from the second story window by firefighters.

The Butler County Sheriff says the couple's 16-year-old son tied his parents' door shut before he set the fire. They also allegedly found diagrams and charts of the boy's plans. That 16-year-old is charged with two counts of attempted murder and one count of aggravated arson.
