In the third and final part of this series, we explore what happened to the mountain of evidence in the 1984 cold case murder of Kelly Jean Robinson -- and we discuss what could come next in law enforcement's investiation into Kelly's death.

Kelly's body was found floating in a rural Minnesota gravel pit pond, roughly 30 miles from her home in Sioux Falls. Her case remains unsolved.

In part 2 of this series, the team at The Vault tries to track down a man previously considered a potential suspect in the 1984 murder of Kelly Jean Robinson. In the process, they run across a new potential person of interest: a convicted murderer who preyed on South Dakota workers in the 1980s. He was a free man in 1984 -- and he was known to frequent The Frontier Bar, where Kelly Robinson was last seen leaving.
