Authorities hope a $20,000 reward offered this week will generate the lead they need to solve the disappearance of a young Lancaster mother who vanished in 2013.

County Supervisor Michael Antonovich recommended the reward in hopes of discovering what happened to Michelle June Russ, who was last seen leaving her residence on the 42000 block of 51st Street West at 11 p.m. on May 9, 2013.

Russ, who was 26 at the time, left behind a young son.

Her twin sister, Christine, told investigators that Russ left home to meet friends around the corner, but never returned.

Family members said Russ had an anxiety disorder and was prone to seizures.

Sheriff’s investigators have exhausted all leads and believe that the circumstances surrounding Russ’s disappearance were suspicious. They are now treating the case as a homicide, according to sheriff’s Detective Steve Lankford.

Antonovich urged anyone with more information to call Lankford at (323) 890-5500.

“We’re just looking for any help we can get,” Lankford said.
