Kanchanben Patel and her husband, who worked at the motel, were hit by the youth who had an altercation with them about illegal use of a room.
Moses Acloque, 22, hit Kanchanben with his pickup truck and dragged her for three miles, killing her, police said.
Acloque was arrested in Foxborough late Monday night just after a state trooper reported seeing the body of Kanchanben under his Ford F150 vehicle.
After smashing one car, MyFoxBoston reports, he struck Kanchanben and her husband.
Acloque was arraigned this morning in Wrentham District Court on multiple charges, including leaving the scene of an accident causing death, prosecutors said.
