COOS BAY — A Coos Bay woman is missing after leaving her apartment Thursday night. Thirty-four-year-old Holly Berry was officially listed as a missing person Sunday, days after police and family began combing the streets for clues on her whereabouts. Berry's family says she left her apartment on Norman Street in Coos Bay around 4 p.m. to possibly go grocery shopping at Walmart or Grocery Outlet. The 5-foot-2, 140-pound Berry lives alone in the apartment and was last seen wearing a purple and white jacket with a gray and pink backpack. Berry's family said she is part of the mental health community and has not had her medication since she went missing. 'She's vulnerable," her stepfather Jay Maxner said. 'She hasn't had her medication for three days. She's in trouble in that (sense)." Berry's mother, Pearl Maxner, described her daughter as someone who is very shy and loves to knit. The family said Berry held a part-time job at the North Bend Library and enjoyed going to mall for knitting class. 'She takes knitting hats everywhere she goes," Pearl Maxner said. Jay Maxner said his stepdaughter only walked to buy groceries and took a cab everywhere else she went. Berry likes to wear multiple bracelets around her wrists and her mother said she always has her hair pulled back in a ponytail. The Coos Bay Police Department had not released any new information about Berry's disappearance as of early Monday morning. Berry's family said she would never hitchhike or get into a stranger's car. They said they believe wherever she is, it's close by. 'She has a real small world," Jay Maxner said. 'Wherever she is, it's probably fairly close to her home." Berry liked to go for walks in the Empire Lake area, but both her parents said she has never gone on a walk there alone. The last time Berry was known to be in contact with her parents was Thursday morning when she called her mother. Anyone with information on the disappearance of Holly Berry is urged to call the Coos Bay Police Department at 541-269-8911.
