Male, age 36, Lyman “Lyman Marshall” Klein left his small home in Manley Hot Springs, Alaska, on May 17, 1984, for a casual trip to the Tanana River boat landing with his pregnant wife, Joyce and their two-year-old son, Marshall. The landing was a familiar gathering spot for the tight-knit hamlet west of Fairbanks; that afternoon, several neighbors also drifted in and out. By evening, worry replaced routine. Families realized that Klein and the others had not returned. Calls went out to Alaska State Troopers in Fairbanks the next day, describing multiple missing residents and a stranger often seen loitering at the landing.
Troopers quickly learned the stranger's name: Michael Alan Silka, a 25-year-old drifter already wanted for questioning in the recent disappearance of a Fairbanks man, Roger Culp. Before the disappearances at Manley Hot Springs, officers had examined Silka's remote cabin; they initially accepted his explanation that blood seen there came from a moose hide. By May 8, with new witness accounts and human blood found near the cabin, Silka had vanished from Fairbanks. He surfaced in Manley Hot Springs on May 14, camping near the Tanana and paddling a canoe—behavior locals noted in the days leading up to May 17.
In the predawn hours of May 19, aircraft and an emergency response team swept the river country. Searchers found blood and spent casings at the landing, then tracked Silka upriver to an unnamed tributary of the Zitziana. When troopers attempted to take him, Silka stepped from cover and fired a. 30-06 into a helicopter, killing Trooper Troy L. Duncan and wounding another officer. Troopers returned fire from the air, fatally shooting Silka on the riverbank. With the gunman dead, the search shifted to recovery. By late June 1984, the Tanana yielded four victims' remains—including Klein along with Dale Madajski and Larry Joe McVey—confirming that the missing had met violence along the water.
Klein's killing fit into a broader spasm of violence that claimed up to nine victims in Alaska that spring, centered on Manley Hot Springs. News accounts from the time recorded that the group of missing included a pregnant woman and a toddler—the description matching Klein's family. Subsequent memorial and burial records list Lyman Marshall Klein's death as May 17, 1984, in Manley Hot Springs, and later community remembrances and victim registries identify him as lost to gun violence that day.
As to arrests, there were none in Klein's case. The sole suspect was Michael Silka, who died in the shootout with troopers on May 19, 1984, ending any prospect of a prosecution. Authorities and reporters connected him to the cluster of killings and disappearances at Manley Hot Springs; Klein is among the named victims in those reconstructions of events. Klein's wife, Joyce, and son, Marshall, were also counted among the missing, with reports noting that some bodies were believed to have been consigned to the fast, ice-cold, silt-heavy Tanana River, where remains can be difficult to recover.
