As an FYI, all unattended deaths in MA (Outside of the larger cities) fall under the jurisdiction of the State Police. The locals will be marginally involved and any heavy lifting will be done by the MSP.
They already have the autospy report (that stuff is done in a few days.). The tox report will take 1-2 months.
This will be closed by labor day. My guess, knowing relatives in the MSP, is that it will be an accident and sealed up tight.
Just one of the Departed.
