A former Montgomery County man accused of killing two teenagers in a marijuana-fueled crash is heading to trial on new charges.

Austin Ewers, 21, formerly of Lower Pottsgrove, waived his preliminary hearing today in Lawrence County.

He was charged with driving drunk in New Wilmington back in November.

In 2009, Ewers was just 16 years old when he was charged with driving under the influence of marijuana and causing a crash that killed two people and injured several more.

He was released from a juvenile treatment facility when he turned 18.
