Is there a possibility for it if he gets convicted for the double murder?
Not according to Massachusetts | Death Penalty Information Center
The last executions to take place in Massachusetts were Phillip Bellino and Edward Gertson on May 9, 1947 for the murder of Robert William. Both defendants were electrocuted at Charlestown State Prison. Their executions inspired a commission to evaluate the death penalty in Massachusetts to determine the effectiveness.
Milestones in abolition/reinstatement
After Furman v. Georgia, voters in the Commonwealth passed an amendment that allowed the death penalty in 1982. Under this new amendment, the state could not "be construed as prohibiting the imposition of the punishment of death". Later that same year, the legislature passed a bill reinstating the death penalty for first-degree murder.
In Commonwealth v. Colon-Cruz (1984), the Massachusetts law that enabled capital punishment was ruled unconstitutional on the grounds that it was not applied fairly, since only defendants who went to trial were eligible; this excluded defendants who plead guilty.
