A Lisbon man has pleaded guilty to stealing federal property from the home where a quadruple homicide occurred.

Arden Shaw, who is in his 50s, was one of three people charged with stealing several U.S. Border Patrol items in 2023 from the Eger family home in Bowdoin, including a portable radio, a gun with a mounted light, body armor and badges.

He entered a guilty plea to one count of theft of government property in U.S. District Court in Portland on Tuesday morning, according to court records. He faces up to 10 years in prison.

Patti and Robert Eger were killed in April 2023 while their longtime friends Cynthia and David Eaton were in town. Joseph Eaton — the latter couple’s son — pleaded guilty to their murders and is serving a life sentence in prison.

The Egers’ son, a Border Patrol agent, was living in their home after the shooting when he reported in June 2023 that several items were missing, including jewelry, a laptop and the Border Patrol items.

Police tracked the stolen property to the home of Michael Hall and Jeanne Doughty, who were later charged in state court. (Police have accused them of a broader identity theft scheme. Both cases were still pending Tuesday afternoon, according to a clerk for Sagadahoc County Superior Court.) An attorney representing Hall on the state charges declined to discuss the case Tuesday.

Shaw, Hall and Doughty were charged a year later in U.S. District Court for taking the Border Patrol items, and all have now pleaded guilty. They will be sentenced at a later date.
