On Wednesday, the murder trial of Boston art fraudster Brian Walshe saw Massachusetts police officers, airline record keepers, and a Customs agent take the stand. This marks the third day of proceedings as Walshe faces charges related to the disappearance and presumed death of his wife, Ana Walshe.

Massachusetts State Police Trooper Nicholas Guarino began the day’s testimonies.

This week, Guarino has provided extensive testimony regarding Walshe’s internet search history, which revealed incriminating queries about how to dispose of human remains and how to clean DNA from a knife. Additionally, Walshe searched for classified ads featuring Porsches, diamond jewelry sales, and a pornographic video involving a cheating wife.

Allegations have surfaced that Ana was involved in an affair with William Fastow, a realtor from Washington, D.C., whose name was also among Walshe’s online searches.

Prosecutors suggest two possible motives behind Ana’s murder. One is Walshe’s anger over her affair. The other is his belief that Ana’s absence would improve his chances of avoiding imprisonment for an unrelated art fraud case, as he would become the sole caretaker of their three children.

Walshe’s defense has denied that he had any knowledge of the affair.

Next on the stand was a U.S. Customs and Border Protection agent named William Foley, who testified briefly about Ana’s air travel in the weeks before she vanished.

Next up was Cohasset Police K-9 Sgt. Patrick Reardon, who was part of the search effort for Ana on Jan. 5. 2023, with his K-9 partner, Einstein. Reardon and Einstein participated in an area search outside the Walshe family home. They found nothing of note, except for a dog in a fenced area of the backyard. The defense declined to cross-examine him.

Thomas Menino, a JetBlue corporate security official and records keeper who works at Boston Logan International Airport, took the stand next. He testified that Ana’s flight from Washington to Boston on Christmas Day 2022 had been refunded. She took another flight on the same route from Dec. 30, 2022. She was listed as “no show” on her return ticket, issued for a flight back to D.C. on Jan. 3, 2023.

She missed four more flights later in January that had all been booked earlier, because she commuted to the nation’s capital for work. Ana was last seen on Jan. 1, 2023.

The defense also declined to cross-examine Menino.

Cohasset Police School Resource Officer Gregory Lowrance testified next that Walshe told him after Ana’s disappearance that when he last saw her on Jan. 1, she had departed for a flight from Boston to Washington.

Lowrance took a missing person report from Walshe regarding Ana on Jan. 4.
