Overview
- Massachusetts State Police analysts testified that stains in the basement and on a kitchen knife tested positive for blood, and numerous tools and materials recovered from dumpsters also showed blood.
- DNA experts said profiles on a hacksaw blade, hatchet head, a towel, a stained rug piece and a tissue supported inclusion of Ana Walshe, with Brian Walshe excluded on several items and mixed DNA on a Tyvek suit and slippers.
- A forensic scientist said he documented no blood spatter in the home, while noting that cleaning with bleach, ammonia or even water can hinder blood detection.
- Jurors saw security footage and receipts that prosecutors say track Brian Walshe on January 1 buying cleaning supplies and a hacksaw and discarding a trash bag in a liquor store dumpster, followed by additional purchases on January 2 and 4.
- The medical examiner testified he could not determine a cause or manner of death without a body, as coworkers recounted searching for Ana in Washington, D.C., after Brian reported her missing.
