Authorities say a 41-year-old Helena man admitted that he stabbed and killed another man whose body was found east of Helena last week.
Dewayne William Johnson is charged with deliberate homicide, or in the alternative, accountability to deliberate homicide in the death of 56-year-old Shane White of Helena. According to charging documents, Johnson had knowledge of injuries White sustained that had not been made public and admitted to killing him and identified the knife used.
“Monday, September 23, 2019 (Johnson) admitted to detectives he knowingly and purposely caused blunt force and sharp force trauma to the victim resulting in the victim’s death,” court documents state.
Johnson’ bond was set at $100,000 in Lewis and Clark County Justice Court Wednesday.
His co-defendant in the case, 32-year-old Serena Lee Kilseimer of Helena, appeared in Lewis and Clark County Justice Court Monday on the same charges. Kilseimer’s bond was set at $75,000.
Johnson told authorities that Kilseimer was present during the homicide, court documents state.
White, of Helena, was reported missing Sept. 16 by a family member, who told authorities that White was last seen at his residence with Kilseimer and Johnson.
The three were captured on security camera footage Sept. 8 on Canyon Ferry Road and Johnson, who wears a GPS monitor related to other charges, was tracked east of Helena to the area of Cave Gulch near Canyon Ferry Reservoir, according to court documents. A witness later observed Johnson return to White’s residence in his truck but without White, court documents state.

Johnson was arrested Sept. 9 at White’s residence on a warrant related to burglary and assault charges from 2018. As part of his release, Johnson was required to wear a GPS monitor, and the warrant was issued after he fell $640 behind on payments and failed to keep the unit charged, according to court documents.
Kilsemeir was present during the arrest and when asked about White’s whereabouts, Kilseimer reportedly said, “I’m not talking about any murders,” court documents state.
On Sept. 18 authorities and members of White’s family went to Cave Gulch to search the family’s property. There, they located White’s body along with two knives located nearby, with one believed to have blood on it and matching Johnson’s description, according to court documents.
White’s cause of death was determined by autopsy to be a homicide and the result of blunt force trauma and sharp force trauma.
Authorities say that White had testified against Kilseimer and Johnson in a previous dependent neglect case, but court documents do not specify that as an alleged motive.
Johnson requested that his bond be lowered during Wednesday’s hearing before Judge Bob Wood, but was denied.
All suspects are presumed innocent until proven guilty.
