York Regional Police are asking for the public’s help to locate a Vaughan woman who hasn’t been seen since she left a hospital in Toronto last week.

Police say 30-year-old Catherine (Cathy) Keum was last spotted leaving a hospital in the Keele Street and Wilson Avenue area at around 11:30 a.m. on Nov. 17.

Police wouldn’t say why Keum was at the hospital, but they said they believe she is in a vulnerable state and are concerned for her well-being.

Investigators believe Keum may be somewhere in Toronto at the moment.

She is described as an Asian woman with a thin build, standing around five-foot-six. She was last seen wearing a bright blue waist-length parka with a fur-lined hood, grey pants and running shoes.

Anyone with information about Keum’s whereabouts is asked to contact the York Regional Police #2 District Criminal Investigations Bureau at 1-866-876-5423, ext. 7241 or call Crime Stoppers anonymously at 1-800-222-tips.
