Jon Dilley was sentenced to consecutive 30-year sentences.
71-year-old Sarah Murray and 41-year-old Chellie Calloway were shot dead in August of 2004 at Murray’s home in Boothbay Harbor.
Dilley had argued that the shooting deaths were not separate episodes, and not serious enough to warrant consecutive sentences.
Dilley was tried for murder but found guilty of manslaughter.
The supreme judicial court unanimously upheld those two manslaughter convictions and the trial judge’s imposition of the maximum sentence on each count.
