New details reveal marriage in crisis before Ana Walshe murder case in Fox Nation special

Conman Brian Walshe's suspicious internet searches and his mother's string of inquisitive voicemails take center stage in a new Fox Nation special on the Ana Walshe murder case, offering a closer look at the strained family dynamics that preceded the Massachusetts mother of three's disappearance.

"I wanted to hire a private investigator to just get some information on my daughter-in-law," said Diana Walshe, her voice muffled through the phone.

The recording offered a glimpse into the family's growing concerns before Ana Walshe vanished, undercutting the image of a picture-perfect marriage and suggesting deeper tensions behind closed doors.

The high-profile case is the focus of a new Fox Nation special, which retraces the events leading up to Walshe's disappearance and explores the cracks in the couple's seemingly idyllic life through interviews and previously documented evidence.

"They appeared to be an ideal couple living in a very affluent enclave in Massachusetts," former prosecutor Josh Ritter recounted.

But all was not as it initially seemed. Boston-based reporter Bob Ward described the difficulties brewing under the surface that would eventually reach a boiling point.

"Her marriage was in complete shambles, and there was no way to repair it," he said.

The same day that Brian Walshe's mother made her call to private investigator Jereme Dozier, Brian searched the internet for information regarding divorce. According to Dozier, Diana made the call under the assumption that Ana was having an affair with a close new contact in the D.C. area named William Fastow.

Evidence appeared to support the suspicion and Ana's private conversations indicated she was prepared to move on with her life.

But those plans were destroyed in early January 2023 when a phone call from Washington, D.C. police to a local department in Cohasset, Massachusetts shattered the peace.

"Her coworker from security was reporting that she had not shown up for work, and that was not consistent with what he knew about Ana and her work ethic," William Quigley, chief of the Cohasset Police Department, told the show.

"We found it very odd that the husband didn't contact us immediately when he hadn't heard from his wife in days, especially with having three small children," he added.

Brian Walshe's story centered on a "work emergency" that demanded Ana's attention in Washington, D.C., so she fled to address the issue. When confronted by the authorities, he insisted he hadn't heard from her since.
