Feds: Seminole man pleads guilty in connection to 2 killings

October 20, 2021 GMT

MUSKOGEE, Okla. (AP) — A Seminole man who was a member of a Native American prison gang pleaded guilty Wednesday to charges connected to separate homicides, federal prosecutors announced.

Matthew Onesimo Armstrong, 32, a member of the Seminole Nation of Oklahoma, pleaded guilty to assault with a dangerous weapon and to using a firearm during a crime of violence in connection with the May 2015 killing of Scotty Candler. Another man, John Douglas Knight, has been charged with killing Candler, and a jury trial in that case is set for January.

Armstrong also pleaded guilty to murder in Indian Country and kidnapping in connection to the April 2017 killing of Nicole Owl near Armstrong’s home in Seminole, Oklahoma, prosecutors said. According to an FBI agent’s affidavit in the case, Armstrong believed Owl stole money and drugs from him, tied her to a tree, shot her twice and then helped bury her in a shallow grave.


Messages seeking comment from Armstrong’s attorneys weren’t immediately returned on Wednesday.

Prosecutors say Armstrong admitted in a plea agreement that he was a member of the Indian Brotherhood, a prison gang active in Oklahoma.

Armstrong faces up to life in prison when he’s sentenced in a few months.
