Cheryl Anne Troy was 50 and vice president for human resources at Edgewater Technology when she arrived at the Wakefield, Massachusetts, office on the morning of December 26, 2000. An employee, Michael McDermott, began a methodical attack inside the suite at 200 Harvard Mill Square, moving through the lobby and offices with multiple firearms. Prosecutors and contemporaneous reports indicate Troy was among the first struck near the reception area as she tried to flee; she died at the scene along with six colleagues.

Responding officers encountered McDermott in the building lobby and arrested him without further gunfire. He was charged with seven counts of murder; prosecutors said he had brought an AK-type rifle, a shotgun, and a handgun into the office and was allegedly motivated by anger over a wage garnishment for back taxes. A Middlesex County jury convicted him in April 2002 on all seven counts of first-degree murder, and he received seven consecutive life sentences without the possibility of parole. Troy’s name appears on official accounts and memorial lists of those killed.

Did anyone who knew Cheryl Anne Troy or worked at Edgewater Technology that day notice anything about her schedule or who she spoke with that morning?
