(St. Joseph County, IN) - An arrest has been made for the deaths of two people in a motor vehicle crash last year between New Carlisle and South Bend.

Charges were filed against 46-year-old Thongkhoun Phommaha of South Bend, whom authorities say veered over a center line in the road and collided with an oncoming motorcycle, killing its occupants: 59-year-old Mark Pierce and 54-year-old Jane Ryall.

The accident happened in July on U.S. 20 west of Quince Road.

Phommaha has been charged with two counts of Causing Death with a Controlled Substance in his Bloodstream.

Each count could bring him anywhere from a 2 to 12-year sentence.
