An 82-year-old man who was severely beaten in downtown Portland, Oregon, last month died Thursday night after battling for his life for nearly two weeks. The Medical Examiner’s Office concluded that Donald A. Pierce died from blunt trauma after carrying out an autopsy on the body, the Portland Police Bureau said in a Tuesday news release. More chargers await Pierce’s assailant 29-year-old Keffer White, who presently faces two counts of attempted first-degree murder, one count of first-degree assault and one count of second-degree assault, KPDX-TV reported. Police were responding to a call involving a separate incident near Southwest Fifth Avenue and Southwest Hall Street on June 25 when they spotted White assaulting Pierce and 88-year-old Allen Lichtenstein, according to reports from KXL-FM and KGW-TV. The incident occurred at around 8:30 p.m. that day near Portland State University, according to Oregon Live. According to police, White punched the two men several times and even toppled them over, Oregon Live reported. White kicked the elderly men while they were lying on the ground and even headbutted one of them, KXL-FM reported. The assailant was also laughing at his victims because they were “old men,” police said, according to the station.
