TENINO – A man arrested for the murder of a Tenino mother said he accidentally choked her and dumped her body on his property, court documents state.

Eric Roberts has been arrested for killing Nancy Moyer in 2009. Investigators are searching his property in Rochester for Moyer’s remains.

Thurston County Sheriff John Snaza said Roberts called 911 on Tuesday saying “I killed her,” claiming to have strangled her with a scarf during “rough sex.” However, in follow up interviews with detectives, Roberts recanted his confession saying he didn’t know why he said he killed Moyer.

Detectives with the Thurston County Sheriff’s Office have been working Moyer’s disappearance for the past 10 years.

Snaza said the man worked with Moyer at the Department of Ecology at some point.

On Wednesday, several agencies conducted a search at a property in Rochester. Snaza said law enforcement recovered evidence that will be sent to the state crime lab.

Moyer, a 36-year-old mother of two, disappeared from her Tenino home in March 2009.
