(Bristol, IN) - We now know how many pigs were killed when the truck hauling them overturned in northern Indiana. The accident happened Thursday near Bristol.

Indiana State Police said 165 pigs were in the semi-trailer. Fifty of the pigs were killed. Another 13 pigs had to be euthanized due to injury under figures released Monday.

The driver of the hog truck was driving too fast, going into a curve, and the weight of his load shifted, causing the rig to overturn.

The driver, Justin Chastain, 19, of Rensselaer, suffered just minor injuries and refused medical treatment.

Police said he was heading to a meat processing plant in Logansport from Michigan.
