Overview

• A motion filed Wednesday seeks to relocate the Oct. 20 Norfolk Superior Court trial or seat jurors from outside the county, arguing Brian Walshe cannot get an impartial jury.
• The filing cites years of extensive media coverage and notes a recent stabbing attack on Walshe at the Dedham jail where he is held without bail.
• Prosecutors’ new filings preview their motive theory, pointing to knowledge of an extramarital relationship, concerns about sentencing in a federal art fraud case, and potential life insurance proceeds.
• The state says it will present items with Ana Walshe’s DNA recovered from a Swampscott dumpster near Walshe’s mother’s home, including a distinctive rug and jewelry, plus expanded internet history evidence.
• Key Google searches about dismemberment and disposing of a body were cleared for use by the state’s high court last month, while the defense moves to exclude prior bad-acts evidence and limit affair-related testimony, with both sides proposing jury questionnaires.
