Born Tanisha Hopkins and originally from Newburyport, Massachusetts, he has lived in the Biddeford-Saco area for much of his life, legally changing his name to Connor MacCalister in January 2005, according to court documents.
MacCalister lived in at least one group home in Biddeford and also had an address at a subsidized housing complex in Saco that serves adults with mental disabilities. Court documents from 2011 indicate that MacCalister didn’t work and lived on General Assistance. He also had applied for Supplemental Security Income.
Though MacCalister’s current address on Therrien Avenue in Saco was just one street from Boudreau’s house, police don’t believe MacCalister and Boudreau knew each other. Neighbors said MacCalister lived in an apartment at Kallock Terrace, an Avesta housing development.
According to Avesta’s website, Kallock Terrace’s subsidized apartments are designed for persons 62 and older who are disabled.
It appears to be related to the Irish/Scottish Gaelic name, Mac Alasdair, a clan associated with the Scottish clan of the Mac Donalds, derived from the personal name Alexander. MacCalister, thus means, in essence, "son of the defender of man."
