Metro is looking for an 81 year old Las Vegas woman who disappeared four days ago.

Opal Parsons has been missing since Thursday.

When her daughter came home from work, she found the lights and TV on, a key in the door, her mother's van parked in the driveway, but no sign of her mother.

The next day the woman's driver's license and social security card were found on the floor of Sam's Town casino.

Metro detective Dan Holley is investigating whether foul play is involved.

The case is still in its early stages.  Metro says it is classified as an endangered missing persons case until their investigation is complete.
