OLYMPIA, Wash. (AP) – A man who police say confessed to killing a Tenino mother a decade ago will not face any charges at this time.

The Olympian reports Eric Lee Roberts was released from federal custody after the Bureau of Alcohol, Tobacco, Firearms and Explosives decided not to pursue illegal firearms charges.

Roberts was arrested last week on suspicion of murder in the death of Nancy Moyer after police say Roberts called 911 July 9 to confess to killing his former neighbor in 2009, but he then recanted.

Detectives said they found guns at his home and in a complaint Wednesday, the Bureau of Alcohol, Tobacco and Firearms said an AM-15 multi-caliber rifle with a short barrel was illegal to possess.

A spokesperson for the U.S. Attorney’s Office for the Western District of Washington says “further analysis indicated this weapon did not necessarily meet that legal definition.”
