A search this week of a property in western Pennsylvania came up empty in the latest effort to find 8-year-old Cherrie Mahan who disappeared in 1985.
The Pennsylvania State Police and a team from the Mercyhurst University Archaeological Institute this week searched a property in Butler County.
Police say the continued investigation and interviews led to the searches. They brought search dogs to the property and the Mercyhurst team excavated part of it.
Cherrie Mahan was last seen by a motorist stepping off a school bus near her home in Cabot, about 25 miles northeast of Pittsburgh on Feb. 22, 1985.
Later that year, she was featured on the first "Have You Seen Me?" mailings by Advo Inc.
