COHASSET, Mass. (NewsNation) — Brian Walshe, the husband of missing Boston mom of three Ana Walshe, is expected to be arraigned in court on Wednesday.

“Mr. Walshe will be transported to the Quincy District Court for arraignment on a charge of murder. Additional details of the investigation and the evidence in support of those charges are likely to be presented at arraignment but will not be disclosed at this time,” Norfolk District Attorney Michael Morrissey said.

The 47-year-old was charged with murder and the improper transport of a body in connection to his wife’s disappearance, Morrissey announced Tuesday. 

Ana Walshe, 39, was last seen on New Year’s Day.

“The continued investigation has now allowed police to obtain an arrest warrant charging Brian Walshe with the murder of his wife,” Morrissey said.

Ana, 39, was last seen New Year’s Day, leaving her Massachusetts home to fly to Washington, D.C., where she worked and owned a condominium. She was reported missing three days later by her husband. However, the Daily Beast reports that Ana may have been reported missing by her employer before Brian.

Cohasset police first arrested Brian four days after Ana was reported missing, accusing him of lying to investigators about his whereabouts in the days after Ana disappeared.

He was charged with misleading investigators in the search for his missing wife.

In court, prosecutors said they found blood in the couple’s basement along with a broken bloody knife. They also had surveillance video of Brian buying hundreds of dollars in cleaning supplies at a Home Depot — a trip they said he failed to mention.

Sources told Los Angeles Magazine that Brian allegedly dismembered Ana in the basement of their home and took her remains to an incinerator site. The source also said police may never find a body.

NewsNation has not been able to independently confirm that report.

Searches of Boston-area trash facilities revealed additional evidence. Investigators reportedly discovered a hacksaw, blood and a rug.

Now, investigators said they have enough evidence to support both of those new charges.

However, police have not said whether they found a body.

The arraignment is expected to reveal more about the biological evidence investigators discovered.
