The search continues for a missing Casper woman, and the reward in the case has grown.

Casper Police say an anonymous donor has contributed $5,000, thus increasing the total reward to $30,000, for information leading to finding 61-year old Kristi Richardson, and/or anyone who would be prosecuted, if the case turns criminal.

Richardson was first reported missing in early October, and is described as 5 feet 4 inches tall, weighing about 115 pounds.

Earlier this month, her family announced a $25,000 reward, in an attempt to move the investigation forward.

The Casper Police Department has been working with the Federal Bureau of Investigation and the Wyoming Division of Criminal Investigation on this case.
