A personal support worker caught on video repeatedly punching an elderly man in the head apologized to the man’s family, saying he would accept whatever sentence the court decided. Jie Xiao pleaded guilty in July to one count of assault in connection with the attack four months earlier on 89-year-old Georges Karam. Xiao, speaking in Mandarin through a translator at his sentencing hearing Thursday, told Karam’s family he was “deeply sorry for what I did.” Xiao, a 44-year-old permanent resident, told the court he did not intend to hurt Karam, but that in that moment he failed to remember his duty to his client. “I have used the wrong way of doing things,” he said.
