Roger Francis Culp Disappearance

Roger Francis Culp disappeared on April 28, 1984, from the Chena Ridge area outside Fairbanks, Alaska. He was 33 years old. His disappearance would later become widely believed to be the first known victim connected to Michael Alan Silka, whose violent crime spree shocked Interior Alaska just weeks later.

According to investigators and witness accounts, Culp was last seen entering Silka’s cabin. Neighbors later reported hearing numerous gunshots coming from the residence that same day. When Alaska State Troopers questioned Silka the following day, he explained away visible blood by claiming it came from processing a moose hide. Without sufficient evidence at the time, investigators were unable to arrest him.

Over the following days, suspicions grew. On May 8, 1984, troopers returned with a search warrant and located evidence that the blood inside the cabin was human. By then, however, Silka had disappeared.

Just days later, Silka surfaced near Manley Hot Springs, where investigators believe he murdered several more people in one of Alaska’s most notorious killing sprees. Between May 17 and May 19, multiple residents vanished before Silka fatally shot Alaska State Trooper Troy Duncan during an aerial search. Another trooper returned fire, killing Silka and ending the manhunt.

Although several victims from the Manley Hot Springs murders were eventually recovered from the Tanana River, Roger Francis Culp has never been located. Investigators believe he was likely killed inside Silka’s cabin and that his remains may also have been disposed of in the river, but no physical evidence has ever confirmed exactly what happened after his disappearance.

Because Silka died during the 1984 confrontation with law enforcement, the investigation into Culp’s disappearance could never proceed to prosecution. Nevertheless, modern case summaries from researchers and investigators continue to identify Roger Francis Culp as Silka’s likely first victim.

Latest Investigation Information

There have been no publicly announced forensic breakthroughs, arrests, or newly released evidence in recent years specific to Culp’s disappearance.
