The Brian Walshe murder trial continued Tuesday with more testimony from police who investigated the disappearance of his wife Ana Walshe from their home in Cohasset, Massachusetts.

The first witness, Cohasset Police Sgt. Harrison Schmidt, was back on the stand Tuesday morning. Prosecutors played audio from Brian Walshe's interview with police that took place in the family's dining room while Ana Walshe was still considered missing.

Later on, Massachusetts State Police Trooper Nicholas Guarino took the stand and testified about Walshe's allegedly violent online search history. Guarino, who said he is on medical leave from his job, also testified earlier this year in the high-profile Karen Read murder trial.

Brian Walshe interview with police

In the audio interview played for jurors, police ask Walshe where he thinks his missing wife is.

"A lot of people have said maybe she's at a spa, you know, she was under a lot of pressure," he responded. "That doesn't really track with my wife, she loved her job and she loved her family."

Walshe is also asked if he'd ever hurt his wife.

"No, I would never do that," he responded. "My wife and I got along very, very well."

In an interview the next day, police asked Walshe about gruesome searches on his son's iPad that include how to "dispose of a dead body." Walshe said he does not know anything about the searches, and was arrested soon after.

During cross-examination, Schmidt acknowledged that the searches were not actually conducted on the son's iPad, but were synced to the iPad from another device. 

Brian Walshe's Google searches

After Guarino took the stand, he read through a binder of Google searches that the prosecution alleges were made by Brian Walshe. Guarino says he pulled the internet searches off of Brian Walshe's laptop from the day his wife Ana went missing.

"So the title for this one is "10 ways to dispose of a dead body (if you really need to)," Guarino said.

Guarino said other Google searches included, "how long does DNA last" and "how long before a body starts to smell."

Other alleged searches read aloud by Guarino included "How long for someone to be missing before inheritance?" and "Best ways to dispose of body parts after murder."

Guarino also recited searches that were allegedly made before Ana Walshe's death, including "Best divorce strategies for men" and "Washington D.C. divorce lawyers."

The defense argues that none of the searches proved that Walshe planned to kill his wife in advance. 

"You saw nothing in the data dating back to 12/25 that indicated any searches that were relevant to how to dispose of a body?" defense attorney Larry Tipton asked. 

"That's correct," Guarino said.

WBZ-TV legal analyst Jennifer Roman says some of the language in these searches contradict the defense's theory, that Walshe found Ana dead and acted out of panic. 

"The prosecution is definitely trying to paint Brian Walshe as somebody who had a motive, both financially and emotionally, that his marriage was done," Roman said. 

Jurors were also shown photos of Ana's boots and her COVID vaccination card removed from a dumpster, along with a cut on Walshe's thumb the day he was arrested. 

On Wednesday, testimony is expected from Uber, Lyft, and JetBlue representatives, along with someone from U.S. customs. 

Brian Walshe trial opening statements

Both sides presented opening statements on Monday, with Walshe's defense offering an explanation for what they called his wife's "sudden and unexplained death" on Jan. 1, 2023. Brian Walshe has admitted to improperly disposing of Ana Walshe's body and misleading police during their investigation, but pleaded not guilty to murder.

Defense attorney Tipton told jurors that Walshe found his wife dead in their bed after a New Year's Eve dinner party, and panicked because he was worried about what would happen to his three children.

"He never thought anyone would believe that Ana Walshe was alive one minute and dead the next," Tipton said. "And so he told a story. He told lies. He tried to hide, so he could hang onto those boys."

The prosecution said jurors will see evidence including a hatchet and hacksaw, and get financial records showing that Brian Walshe was the beneficiary of more than $1 million in life insurance for Ana Walshe. 

Prosecutor Greg Connor said that Ana Walshe was having an affair and was not with the family for recent major holidays. Brian Walshe told police in interviews that they were a happily married couple, but he did not want to have an argument with his wife about missing another holiday.

"He says they were very happy and biggest problem was that they were apart," Connor said.  

Who is Brian Walshe?

Walshe, 50, faces life in prison without the possibility of parole if he's convicted of first-degree murder. In a separate case last year, he was sentenced to three years in prison on art fraud charges.

Walshe originally told police that his wife left early on New Year's Day to get a ride to the airport and fly to Washington, D.C. for a work emergency, but investigators said there was no evidence she boarded a plane.

Ana Walshe's body has never been found. Police said they found a damaged and bloody knife in the basement of the couple's home.
