Missing Rapid City women believed dead, cash reward for anyone with info

A 21-year-old Rapid City woman is still missing, and is believed to be dead.

Larissa Lonehill was last seen in Rapid City in Oct.

Detective Nick Davis with the Rapid City Police Department said while evidence leads them to believe that Lonehill is dead, it will remain a missing persons case until they confirm her whereabouts.

Police are offering a $5,000 reward for anyone that comes forth with information.

Other than asking for help, police are not giving out many details to preserve the integrity of the investigation.

Davis said they have received new information as they are actively searching for answers each day.

"Our job is to look at it and figure out whether there's any credibility to it. So every tip that comes into us we look into,” said Davis. “At least two or three detectives are looking into every single tip that comes in. There's new information on a daily basis that we're trying to get through."

If you have any information on the disappearance of Lonehill call 605-394-4134.
