QUINCY, Mass. (WPRI) — The husband of a Cohasset woman who’s been missing for more than two weeks faced a judge Wednesday morning.

Brian Walshe, 47, was arraigned on a charge of assault with intent to murder, as well as a charge related to moving a body. He has been ordered held without bail.

The charges are connected to the disappearance of his wife, 39-year-old Ana Walshe, who was first reported missing earlier this month. Her body has not yet been found.

Prosecutors believe he dismembered his wife and disposed of her body.

Ana Walshe was last seen by a relative early on Jan. 1, when it is presumed she was heading to Logan Airport. Investigators said she had booked a flight to Washington D.C., where she works, but never boarded the flight.

Brian Walshe has been in custody since he was arrested on a charge of misleading a police investigation.

Prosecutors said that on the morning his wife went missing, Brian Walshe used their son’s tablet to search “how long before a body starts to smell,” “how to stop a body from decomposing,” “10 ways to dispose of a body,” and “can you be charged with murder without a body,” among other topics.

On Jan. 2, Brian Walshe was seen on surveillance video at a home improvement store where he allegedly bought hundreds of dollars’ worth of cleaning supplies. Prosecutors said he also went to Home Goods and purchased new rugs.

Her phone was pinged at the couple’s home on Jan. 2, according to prosecutors, and was then turned off. There has also been no activity on her credit or debit cards.

Prosecutors said the next day, Brian Walshe was witnessed carrying trash bags that appeared to be heavy and disposed of them at an apartment complex in Abington and another in Brockton.

Those bags in Abington were picked up before they could be recovered, according to prosecutors.

Brian Walshe also conducted more Google searches, according to prosecutors, including “what happens to the hair on a dead body,” “what is the rate of decomposition of a body in plastic bag vs woods,” and “can baking soda make a body smell good.”

On Jan. 8, investigators searched the couple’s home and found a bloody knife in the basement.

The search then moved to a transfer station in Peabody, which is where the trash from his mother’s home in Swampscott ends up.

Detectives said they found towels, rags, slippers, tape, gloves, cleaning agents, a Prada purse, Ana Walshe’s COVID-19 vaccine card, a hacksaw, and other items. A portion of a rug was also located, but was heavily stained and had baking soda.

Items in the trash contained the DNA of both Ana and Brian Walshe, according to prosecutors.

Brian Walshe’s attorney released the following statement:

“It is easy to charge a crime and even easier to say a person committed that crime. It is a much more difficult thing to prove it, which we will see if the prosecution can do. I am not going to comment on the evidence, first because I am going to try this case in the court and not in the media. Second, because I haven’t been provided with any evidence by the prosecution. In my experience, where, as here, the prosecution leaks so called evidence to the press before they provide it to me, their case isn’t that strong. When they have a strong case, they give me everything as soon as possible. We shall see what they have and what evidence is admissible in court, where the case will ultimately be decided.”

Brian Walshe is due back in court next month.
