On June 13, 1968, the Lewis and Clark County Sheriff's Office received a call from the custodian at the Gates of the Mountains marina on Holter Lake, after he found what appeared to be part of a human body floating in the water. The part of the body authorities found belonged to a young woman. But the pathologist at the time didn't know how long she had been dead. He did go on to say that it could have been about four months. And that would take us all the way back to February of that year Pamela Ann Dorrington, 19, went missing from Helena, and she would never be seen or heard from again.
