Overview
- Lino, 38, was arraigned in August on two first-degree murder charges in the 2010 death of Gary Melanson in Lowell and the 2012 death of Douglas Leon Clarke in Cambridge.
- Prosecutors allege Lino beat Melanson to death with a metal baseball bat after a dispute over a campfire at a homeless encampment.
- Investigators say Lino killed Clarke by intentionally providing a fatal heroin dose known as a hot shot near the Harvard Square transit area.
- He is already serving a life sentence plus 40 years for two other murders of homeless men, including Norman Varieur in 2012 and Jack Gilbert Berry in 2014.
- Officials say inquiries into possible additional victims continue, and they have not linked Lino to the separate discovery of multiple sets of remains across New England earlier this year.
