COHASSET, Mass. (WWLP) – The husband of Ana Walshe, who has been missing since New Year’s, was arrested for obstructing the police investigation into her disappearance, and was arraigned Monday in Quincy District Court.

Forty-six-year-old Brian Walshe was arrested and charged with imitation of a witness on January 8th, misleading a police investigation. At Monday’s arraignment, prosecutors allege that Brian lied to investigators about the day Ana disappeared and what he was doing that day.

He pleaded not guilty in Quincy District Court Monday morning.

Ana Walshe was last seen at her home on New Year’s Day set to take a ride share to Logan Airport and then board a plane to D.C. on a work-related trip. Investigators confirmed she never boarded the plane, but could not confirm whether or not she got into a ride-share service.

During the court arraignment, the investigation indicated that Ana’s husband reported her missing as well as employees notified police that she did not report for work on Wednesday, January 4th. The only plane ticket Ana had was confirmed for January 3rd to return to D.C. and authorities verified it was not used.

Ana’s cell phone last pinged at her home on Justice Cushing Way in Cohasset on January 2nd, after Brian said she had left.

During this time, Brian Walshe was on house arrest pending federal sentencing in a separate case. However, he told police during the investigation of his missing wife, on January 1st he went to his mother’s house but got lost. He also told police he went to Whole Foods and CVS, but surveillance footage indicated he was not at either place, or receipts were not provided to prove he was there.

As part of his probation, Brian Walshe is required to indicate if he was leaving his house. He only reported that he took his son for ice cream. According to the court hearing, surveillance shows that on January 2nd at around 4 p.m. that he went to the Rockland Home Depot and purchased about $450 worth of cleaning supplies such as mops, a bucket, drop cloths, and various amounts of tape.

A search warrant of Ana’s home found and recovered blood in the basement area and a damaged knife with blood on it.

The Cohasset Police Department said Saturday, “the ground search will not resume unless police develop new information that so warrants it.”

Brian Walshe’s bail was set at $500,000 cash, $500 million surety, and is due back in court on February 9 via teleconference.
