DUNCAN, Okla. - 18-year-old Edward James Jr. plead guilty to being an accessory to the murder of Australian baseball player, Christopher Lane.
A judge ordered Edwards to serve prison boot camp in Oklahoma.
He's due back in court June 2016 where the judge will formally sentence him; he could face up to 45 years in prison.
He's the final defendant in the murder case that gripped the nation in 2013.
Two other teenagers, Michael Jones and Chancey Luna, are serving life in prison.
Luna, Jones and Edwards were in a car when Luna opened fire and shot Lane in the back while he was out jogging.
The baseball player was visiting his girlfriend that weekend.
He was in Oklahoma on a baseball scholarship.
