Brian Walshe allegedly Googled these terms after his wife, Ana Walshe, went missing

Brian Walshe was arraigned on Wednesday on charges of murder and disinterring a body in connection with the disappearance of his wife, Ana Walshe, the Cohasset mother of three young children who was reported missing by her co-workers days after she was last seen early New Year’s Day.

During Brian Walshe’s arraignment on Wednesday, Assistant District Attorney Lynn Beland alleged he dismembered and discarded Ana Walshe’s body. Beland also listed a number of Google searches Brian Walshe allegedly made on and after Jan. 1.

Beland said that there was an additional Google search of note from a few days earlier.

“On Dec. 27, the defendant Googled, ‘What’s the best state to divorce for a man?’” Beland said. “Rather than divorce, we believe Brian Walshe dismembered Ana Walshe and discarded her body.”

These are the terms Brian Walshe allegedly searched online and when, according to prosecutors:

Jan. 1

Brian Walshe told police that Ana Walshe left their Cohasset home Jan. 1 at about 6 a.m. in a ride share heading to Logan Airport for a flight to Washington, D.C., where she worked. But records showed there was no Uber or Lyft to their house on Jan. 1, Beland said during the arraignment.

Prosecutors said that Brian Walshe made the following series of Google searches, starting before dawn.

4:55 a.m.: “How long before a body starts to smell”

4:58 a.m.: “How to stop a body from decomposing”

5:20 a.m.: “How to embalm a body”

5:47 a.m.: “10 ways to dispose of a dead body if you really need to”

6:25 a.m.: “How long for someone to be missing to inherit”

6:34 a.m.: “Can you throw away body parts”

9:29 a.m.: “What does formaldehyde do”

9:34 a.m.: “How long does DNA last”

9:59 a.m.: “Can identification be made on partial remains”

11:34 a.m.: “Dismemberment and the best ways to dispose of a body”

11:44 a.m.: “How to clean blood from wooden floor”

11:56 a.m.: “Luminol to detect blood”

1:08 p.m.: “What happens when you put body parts in ammonia”

1:21 p.m.: “Is it better to throw crime scene clothes away or wash them”

Brian Walshe told police that at 3 p.m. on Jan. 1, he ran errands and went to his mother’s house in Swampscott but claimed he got lost because he didn’t have his phone. He told police he then went to Whole Foods and CVS, but surveillance footage did not show him entering either of those stores.

Jan. 2

Information from Brian Walshe’s phone showed he was at a HomeGoods store on Jan. 2 in Norwell, where he bought three rugs, Beland said. Also that day, he allegedly made another series of online searches.

12:45 p.m.: “Hacksaw best tool to dismember”

1:10 p.m.: “Can you be charged with murder without a body”

1:14 p.m.: “Can you identify a body with broken teeth”

After he allegedly made the Google searches, Brian Walshe was seen on surveillance footage at the Home Depot in Rockland, Beland said. He was pushing a cart with items including cleaning products, mops, brushes, tape, buckets, goggles, and baking soda, Beland said. He was wearing a face mask and rubber gloves while he was pushing the cart.

At 5:32 p.m., he was allegedly seen at the Derby Street Shops in Hingham removing the gloves and a mask.

Jan. 3

The Google searches continued the next day, according to prosecutors.

1:02 p.m.: “What happens to hair on a dead body”

1:13 p.m.: “What is the rate of decomposition of a body found in a plastic bag compared to on a surface in the woods”

1:20 p.m.: “Can baking soda make a body smell good”

At 4:27 p.m., data from Brian Walshe’s phone showed he was at an apartment complex in Abington, Beland said. Video surveillance showed him allegedly getting out of a car near a dumpster while carrying a garbage bag, Beland said.

“He’s leaning and it appears to be heavy, as he has to heft it into the dumpster,” Beland said.

At 4:48 p.m., the prosecutor said, he went to another location in Abington, and at 5:10 p.m., cellphone records show he went to an apartment in Brockton, where he allegedly discarded items in a dumpster, surveillance video showed.

Jan. 4

On Jan. 4, the day Ana Walshe’s co-workers reported her missing and her husband told police he hadn’t seen her since Jan. 1, Brian Walshe allegedly went to HomeGoods and TJ Maxx. There, he purchased towels, bath mats, and men’s clothing, Beland said. At 4:15 p.m., he went to Lowe’s and purchased squeegees and a trash can.
