WASHINGTON, Pa. (AP) -- A Pennsylvania woman has been jailed on charges she drove drunk with her young son to have sex with three people, only to be arrested when a fight broke out. The (Washington) Observer-Reporter (http://bit.ly/1ajnI3S ) says 34-year-old Heather Young was charged by Washington police about 1 a.m. Tuesday. That's when police encountered the Chartiers Township woman after a report of a fight outside an apartment. A man there told police Young had driven there to have sex with three other people. Police say an argument broke out when another woman got angry that Young was undressing in front of her young son. Police didn't release his age, and say the boy's now in his father's custody. Online court records don't list an attorney for Young who is charged with assault, drunken driving and indecent exposure, among other crimes. ___ Information from: Observer-Reporter, http://www.observer-reporter.com
