SUMMIT COUNTY - While neither the Frisco Police Department nor the Summit County Sheriff's Office intends to put McCormick's case on the back burner, it does happen with missing persons cases, said Undersheriff Derek Woodman."Realistically, there are cases that are going to come to head that are going to take some precedence (over McCormick's case)," Woodman said.The sheriff's office has two cases on file that have been inactive for many years.The first occurred in July of 1981, when Tereasa Knuth's boyfriend reported her missing from the squatters camp where they lived outside Frisco where the County Commons now sit.The 23-year-old's purse, money and identification all remained in the couple's converted school bus, but Knuth was never seen again.The most recent work on the case Woodman could recall was in the late 1980s or early 1990s when police received information that Knuth's body could be in the woods near Montezuma. A group searched the area on foot, but never found anything.In November 1990, Michael McClure's roommate reported him missing when McClure never returned home to their Wildernest condo. McClure, 30, had called in sick to his plumbing job the day before, and his roommate hadn't seen or heard from him in more than 36 hours, according to the original police report.McClure's vehicle, a 1972 Chevrolet Chevelle, was never found either.While both McClure and Knuth are still listed as missing people, their cases no longer receive consistent attention, Woodman said."The unfortunate reality is they do kind of go by the wayside," he said. "As new cases go in, we're only able to keep up with what we've got. The harsh reality is they do get looked at very infrequently, I'll bet money that neither of them (has been) looked at in 10 years."Cases are particularly difficult to continue investigating when leads stop coming in, he said.
