Commonwealth v. Duguay

Summary

The court affirmed the denial of Duguay's motion for a new trial and his motion for postconviction discovery. It held that although the particular STR DNA testing was newly available, the additional DNA, serological, seminal-fluid, hair, and phenolphthalein evidence was largely impeaching or cumulative and did not cast real doubt on the conviction; the remaining claims were waived, and the discovery request was speculative. There were no separate opinions.
