Testimony continues on Day 3 of Brian Walshe murder trial

Trooper Nicholas Guarino, who revealed the damning internet searches attributed to Brian Walshe, returns to the stand at Norfolk Superior Court on Wednesday for cross-examination in the murder trial.

Some of the searches that began in the early hours of Jan. 1, 2023, included, “How long before a body starts to smell?,” “How long does DNA last?,” and “How to dispose of a cellphone?”

Walshe is standing trial for allegedly killing his wife, Ana, on New Year’s Day 2023. Prosecutors say he then dismembered her body and tossed her remains in dumpsters around the region, including one near his mother’s home. Investigators never found her body. 

In the days after her disappearance, they say Walshe repeatedly misled police as searches stretched from the couple’s Cohasset neighborhood to Washington, D.C., where Ana worked.

During opening statements, Walshe’s attorney, Larry Tipton, argued that Walshe found Ana suddenly dead after a night of New Year’s celebrations — and then spiraled into a panic. 

On Nov. 18, just before jury selection began, Walshe pleaded guilty to two charges — misleading police and improperly removing or concealing a body. He still faces a first-degree murder charge. Sentencing on the lesser charges will come later.

Norfolk District Attorney Chief Trial Counsel Gregory Connor said upcoming witnesses will include record keepers from Uber, Lyft, and JetBlue; Sgt. Patrick Reardon, the Cohasset K-9 officer on the case; and William Foley of U.S. Customs and Border Protection.

Also expected to testify are Swampscott Police Officer Michael Kenyon and Massachusetts State Police Trooper Amy Waterman.

Other state witnesses include State Police Trooper Connor Keefe (who also worked on the Karen Read case), forensic scientist Davis Gould, and Heather Sullivan.
