After the disappearance of Ana Walshe in Massachusetts, investigators continue uncovering bloodied evidence they believe may be connected to her case.

Since her co-workers reported her missing on January 4, investigators in the coastal town of Cohasset, Massachusetts, have launched a two-day ground search, scoured the family’s home and dug through piles of trash looking for evidence of what happened to the mother of three.

Investigators have already uncovered possible evidence, including a hacksaw and apparent bloodstains in Boston-area trash, according to law enforcement sources. Earlier discoveries included searches in her husband’s internet records related to how to dispose of and dismember a body, law enforcement sources have said.

Prosecutors have said her disappearance is “suspicious” and accused the husband, Brian Walshe, of lying to police to slow the investigation and allow him to clean up evidence.

The 47-year-old husband – who is already awaiting sentencing on separate federal fraud charges – has been charged with misleading investigators in the case. Police allege he gave them a false timeline of his activities and whereabouts around the time his wife went missing. He has pleaded not guilty.

Here’s what we know about the investigation so far.

Law enforcement have searched the home of Ana and Brian Walshe as well as areas north of Boston, the Norfolk County District Attorney’s Office said in a statement Tuesday. The Walshe’s hometown is about 20 miles south of Boston.

The searches north of Boston uncovered “a number of items” which will be tested to determine if they are related to the case, the district attorney’s office said. The office did not share details about the items.

Law enforcement sources told CNN that investigators combing through trash at a transfer station in Peabody – a city about 20 miles north of Boston – found materials they believe could be linked to Walshe’s disappearance, including a hacksaw, torn up cloth and what appeared to be bloodstains.

Crime scene tape was placed around dumpsters at an apartment complex Monday night in the nearby town of Swampscott, close to the home of Brian Walshe’s mother, a source with direct knowledge of the investigation said. The husband told police he visited his mother on January 1, the day he said he last saw his wife, according to an affidavit.

A bloodied, broken knife and bloodstains were also found in a search of the family’s basement, prosecutors said.

Investigators hope to collect blood samples from the Walshe’s sons so they have a “direct bloodline” sample to compare against the traces found in the basement, law enforcement sources said.

Brian Walshe’s attorney declined to comment to CNN.

The husband’s internet records also included searches for “how to dispose of a 115-pound woman’s body” and how to dismember a body, according to two law enforcement sources briefed on the investigation.

The search for Ana Walshe began after her concerned coworkers at the real estate company Tishman Speyer reported her missing on January 4, prosecutors said.

Brian Walshe’s attorney said in court Monday that the husband had reached out to her office in Washington, DC, to say he had not heard from her.

In statements to police, Brian Walshe said he last saw his wife the morning of January 1. She told him she needed to fly to Washington, DC, for a work emergency, the husband told investigators, according to the affidavit.

“Ana got ready and kissed him goodbye and told him to go back to sleep,” he told police, according to the affidavit.

She would typically take a rideshare or taxi to the airport, he told investigators.

But investigators found no evidence of Ana Walshe taking a rideshare from their house that morning or getting on a flight out of Boston, prosecutors said in court Monday. Her phone also pinged near the home on January 1 and 2, according to commonwealth prosecutor Lynn Beland.

“These various statements caused a delay in the investigation,” Beland alleged in court. “During the time frame when he didn’t report his wife, he gave various statements that allowed him time to either clean up evidence (or) dispose of evidence.”

Brian Walsh is under home-confinement conditions as he awaits sentencing on his prior fraud conviction, so he is required to get approval to leave the house at specific times and for particular locations and activities.

He told police he had approval to visit his mother in Swampscott on January 1 and said he ran errands for her at the local Whole Foods and CVS that afternoon, the affidavit says.

Investigators allege those trips “did not occur,” citing their review of video from the stores, the affidavit says.

Brian Walshe also made several unapproved trips the week of his wife’s disappearance, according to the affidavit, including to a Home Depot where he was seen on surveillance video wearing a surgical mask and surgical gloves and making a cash purchase. In court Monday, prosecutors alleged he spent about $450 on cleaning supplies, including mops, a bucket and tarps.

“The fact that he was asked a specific question and he gave an untruthful answer that led investigators out of the area caused a clear delay in the search for the missing person, Ana Walshe,” the affidavit states.

At his arraignment Monday, a Quincy District Court judge set Walshe’s bail at $500,000 cash. He is set to appear back in court on February 9.

Brian Walshe was indicted on federal fraud charges in 2018 for allegedly selling fake Andy Warhol paintings online, according to court documents.

FBI investigators alleged Brian or Ana Walshe used her eBay account to sell the paintings in November 2016, less than a year after they were married. The complaint does not charge Ana Walshe with wrongdoing, but states that she spoke to the person who purchased the fakes after the buyer learned the paintings were not authentic and located her work number.

Prosecutors also alleged Brian Walshe took real artwork from a friend to sell, but never did. He did not compensate the friend for the art, prosecutors alleged.

In October 2018, Walshe was indicted by a federal grand jury on four charges in the case, including wire fraud, interstate transportation for a scheme to defraud, possession of converted goods and unlawful monetary transaction.

Last year, he pleaded guilty to three of the four counts in exchange for a recommended sentence from prosecutors of incarceration, supervised release, fines, restitution and forfeiture, documents show. He also agreed to either return the artworks or pay for them.

According to the online docket, the case remains open as the judge has not formally sentenced him, while the US Attorney’s Office investigates Brian Walshe’s finances.

In a letter to the court dated June 1, 2022, Ana Walshe said she was grateful her husband was able to remain at home as his art fraud case weaved through federal court.

“Brian has been working consistently on breaking the past habits of his family and we are all looking forward to the new chapter of his life,” she wrote.
