later joined Edgewater Technology that same year. In October 2000, McDermott moved out of his apartment in South Weymouth after failing to pay his rent, leaving the residence in a derelict state and owing the landlord $1,720. He then moved into an apartment in Haverhill. It later emerged that, in addition to his other financial troubles, McDermott had owed roughly $5,000 in back taxes to the IRS and that Edgewater Technology had withheld a portion of his wages in order to comply with an order by the IRS. As of 2022, McDermott is incarcerated at Old Colony Correctional Center in Bridgewater, Massachusetts. Media references McDermott is cited in the 2003 psychology book Why We Hate. In 2008, his case was studied on the psychology program Most Evil. Commemorations A cherry tree was planted outside of Edgewater Technology's offices in Wakefield in memory of the seven victims.
