An man who was having an affair with the wife of a Navy reservist pleaded guilty Monday to murdering the man. Andrew Deshawn Canty, 20, will automatically receive a life sentence for first-degree murder in the 2005 killing of Paul Berkley, 46.

Berkley's widow, Monique Berkley, 27, and Canty's friend, Latwon Johnson, 20, also are charged with first-degree murder in Paul Berkley's death.

Investigators accused Monique Berkley of luring her husband to a park on Dec. 18, 2005, so Canty and Johnson could shoot him and the three could share money from Paul Berkley's insurance policy.

Paul Berkley had just returned from a tour of duty in the Middle East. Investigators said he had learned his wife was having an affair and told his daughter he planned to seek a divorce.
