A 61-year-old woman reported missing on Saturday has been located, but the investigation has turned from a case of a missing person to a homicide investigation.

Police were originally called to a home in the 300 block of Varsity Estates Grove NW Saturday afternoon after receiving a report of a missing person.

Guifen Liu was reported missing from the residence. Officers conducted a search of the home and the surrounding area. They were about to expand their search when Liu was discovered in the house.

Police say family members found the woman under the basement stairs at about 6:30 p.m. She was in medical distress and required immediate attention.

Liu was rushed to Foothills Medical Centre where she was pronounced dead of her injuries. Her death is considered suspicious and the Calgary Police Service Homicide Unit is investigating. Police are waiting for autopsy results to come in to determine the cause of death.
