She also claims another person's DNA was found on an HVAC suit along with Ana's. His attorney conceded that the Google searches, which were conducted on their son's iPad, were 'problematic', but claimed they didn't prove murder. Prosecutors laid out again why they believe he killed his wife, pointing to surveillance footage that showed him buying gallon-cylinders, hydrogen peroxide, baking soda, plastic sheets and weapons at various stores after her death, and Google searches about how to remove blood from concrete floors.

Today, Walshe's attorney Tracy Miner said they were indeed 'problematic' for him, before suggesting that Ana had 'disappeared'. That evidence was unveiled earlier this year. Investigators found a multitude of Google searches for how to dispose of a body, how long it takes before a corpse starts to smell and how to clean up blood on their son's iPad in the immediate aftermath of Ana's presumed time of death.

Police say he killed Ana in their Cohasset home in the early hours of New Year's Day, beating her to death then later hacking her bones apart with a hatchet and hacksaw. Walshe appeared in court this morning in Boston, Massachusetts, on first degree murder charges. He was seen arriving clean-shaven, with a new haircut and in a smart shirt and sweater - a stark contrast from his scruffy appearance during past hearings. An attorney for Brian Walshe, the Massachusetts husband charged with murdering his wife Ana on New Year's Day, admitted in court today that Google searches for 'how to dispose of a body' were 'problematic' for him - but still protested his innocence.
