Two people were arrested on Thursday and accused of stealing firearms, money, material possessions and U.S. Border Patrol duty equipment, including government-issued ammunition and a ballistic vest, from the Bowdoin home where four people were shot to death in April.

The Sagadahoc County Sheriff’s Office, the FBI and the Department of Homeland Security obtained a search warrant for a property on Doughty Road in Bowdoin and found “a number” of the stolen items. Michael J. Hall, 40, of Brunswick, and Jeanne I. Doughty, 43, of Bowdoin, were subsequently taken into custody, Sagadahoc County Sheriff Joel Merry said in a statement.

Other items that were found at the Doughty Road residence included a laptop, and a badge, handcuffs, flashlights and ballistic vest plates belonging to U.S. Border Patrol.

Hall was charged with violation of conditions of release and Doughty was charged with receiving stolen property, unlawful possession of scheduled drugs and violation of conditions of release, Merry said. Hall and Doughty were being held without bail at Two Bridges Regional Jail in Wiscasset.

The robbery took place at the site of a quadruple homicide in Bowdoin, where Joseph Eaton is accused of shooting and killing his parents, Cynthia Eaton, 62, and David Eaton, 66, of Florida, and longtime family friends Robert Eger, 72, and Patti Eger, 62, at their home on April 18.

The Egers’ son, Robert, has been living at his parents’ home and reported the robbery on June 19, the sheriff’s office said.

The sheriff’s statement didn’t say how investigators identified the suspects or how the U.S. Border patrol gear came to be at the Egers’ house at 1459 Augusta Road in Bowdoin.

Police say Eaton admitted to shooting his parents and the Egers shortly after he surrendered to officers on April 18. He also is accused of wounding three people driving on Interstate 295 in Yarmouth. During a month-long series of interviews with the Press Herald, Eaton again confessed to the Bowdoin and highway shootings, which wounded Sean Halsey, 51, of Bowdoinham, and his children Justin Halsey, 29, and Paige Halsey, 26.

Eaton, who has a long history of violence and mental health issues, told the Press Herald that he was not in control of his actions when he shot his parents and is considering pleading not guilty by reason of insanity.
