Read / Add Comments Charges have been upgraded for a Bucks County man whose girlfriend died of injuries suffered by him days after an assault, authorities said Tuesday. Evan M. Smith, 37, of Morrisville, was charged last week with aggravated assault, strangulation, recklessly endangering another person, simple assault, and fleeing and eluding. A homicide charge was tacked on for Smith, whose 36-year-old girlfriend, Jamie Beighley -- who had been clinging to life since Thursday -- died on Sunday at Jefferson Bucks Hospital, the Bucks County DA's Office said. Smith apparently choked his girlfriend until she was unconscious at the New Falls Motel at 201 Lincoln Highway in Falls Township, authorities previously said.
