 The man who confessed to killing his parents and two of their friends in Bowdoin last year has been sentenced to life in prison. Joseph Eaton pleaded guilty yesterday to murder and other charges. Police say Eaton confessed to the killings in Bowdoin, as well as wounding three people while shooting at vehicles on I-295 in Yarmouth. The crimes took place just days after Eaton had been released from prison on unrelated charges. Eaton's lawyer said he chose to plead guilty because he believed it was, quote, the reasonable and moral thing to do.
