A West Roxbury man was killed by another convict while in prison at the South Bay House of Correction.
Alexander Callahan, 25, was involved on Sunday with an "altercation with another inmate” according to the Boston Herald.
Callahan was serving time for cocaine possession from charges in June that Patch wrote about, as well as assault and battery.
A Suffolk County District Attorney spokesman said there is an ongoing investigation. Suffolk County Sheriff Andrea Cabral has chosen not to comment, according to the Herald.
According to the Herald, Callahan had a lengthy rap sheet including 14 convictions for drug, assault and weapon charges. There were another nine charges still pending, out of a total 40 drug, robbery, assault and weapon charges filed against him since 2004.
