With tears rolling down her cheeks, Mary Allison recalled happier times as she looked over photos of her older sister, Sharon, who was clubbed to death last year in her Columbia House apartment.She clutched two red roses, one of which represented Sharon Allison’s memory, as she spoke of her sister’s life and death.The hardest part for her, she said, is that she will never have closure.David James Barker, the man accused of killing 66-year-old Sharon Allison, died by suicide in July. He was facing a charge of second-degree murder for allegedly striking Allison in the head with a lamp and dumping her body in a recycling bin inside her apartment.“I have so much anger here. I just want answers. When I read in the paper he killed himself, all I could do was cry because that doesn’t close nothing,” Mary Allison, 59, of Amboy said. “I have to forgive, and I hope I forgive, but that doesn’t mean I like it.”Sharon Allison’s name was one of 76 read aloud during Monday’s annual ceremony for the National Day of Remembrance for Homicide Victims. Her sister came forward to collect a rose on her behalf, as well as a rose for a friend.“I’m very thankful that the news, citizens and everyone involved in her case remember her. She’s not just a number, date of birth, date of death,” Mary Allison said.
