Maine police have reopened the 1980 cold case disappearance of a 25-year-old woman.

The search for Sharon Smith led state and local police on Thursday to an address in Harmon, just outside Bangor, where her boyfriend reportedly lived.

“Over the years different tips have come in that kind of led us up to today,” Bangor Police Sgt. Tim Cotton told Fox Bangor.

Police dug up the front yard with an excavator and then brought in a cadaver dog to sniff the mounds of dirt.

Smith worked at the Paramount Lounge in Bangor. She was reported missing Sept. 4, 1980. She had two children.

The search failed to turn up any remains, the station reported.

Police said in a press release they were also looking for other evidence, including blood, clothing and other items that might contain DNA.

The Bangor Daily News reported that a resident at that address was Smith’s boyfriend George Gilks. He died in 2006 when he was 57, according to his brother who still lives there.

Jim Gilks told the paper that police have been to the house before because they suspected his brother in Smith’s disappearance.

“Never could have happened here,” he said. “This has been gone over and gone over.”
