Fastow, a Washington, D.C. real estate professional, testified that he and Ana Walshe were in an intimate relationship. He said he sold Ana the townhouse where she was living in D.C., and the two began spending time together at dinners, bars, and social events. Their relationship grew closer, and they started communicating daily and eventually spending holidays together.
Fastow told jurors Ana was concerned about how her husband, Brian Walshe, would learn about the relationship.
“Ana felt it was really important that when Brian was to find out about the relationship, that she would hear it from her,” Fastow said. “She had expressed great concern. I think she felt it would be a strike against her integrity if he found out a different way.”
Norfolk Superior Court Judge Diane Freniere ruled that text messages between Ana and Fastow will be admitted into evidence, though some portions may be redacted.
While on the stand, Farstow spoke about the last message he received from Ana Walshe.

The court on Thursday also announced that sentencing on two charges Walshe has already pleaded guilty to — disposing of Ana’s body and lying to police — will be postponed until after the jury reaches a verdict on the murder charge.
During Wednesday’s proceedings, the panel of jurors was shown grim and critical evidence uncovered during the investigation into the disappearance and death of Ana Walshe, who hasn’t been seen since New Year’s Day 2023.
Evidence pulled from dumpster in Swampscott
Ana has never been found, but prosecutors presented items recovered from a dumpster near Walshe’s mother’s home in Swampscott, including:
- Ana Walshe’s clothes, jacket, boots, slippers, pocketbook, headphones, car keys, and her COVID-19 vaccination card
- A Tyvek suit and goggles
- Tools such as a hatchet, hacksaw, hammer, and wire snips
- Pieces of a bloody rug resembling one seen in a photo of Ana in their Cohasset home
Investigators say surveillance video captured Brian Walshe buying cleaning supplies at area hardware stores before reporting his wife missing. They also allege Walshe searched online for ways to dispose of a body and clean up after dismemberment.
Walshe has pleaded not guilty to first-degree murder.
Defense claims natural causes
Walshe’s attorneys argue Ana died of natural causes and that Brian panicked when he found her dead in bed in their Cohasset home, although he has pleaded guilty to disposing of her body and lying to police. They point to earlier internet searches showing someone shopping for a 4-carat diamond ring and a Porsche as evidence that the couple was happy.
Jurors also learned Ana Walshe had two life insurance policies worth more than $1 million, with Brian listed as the beneficiary.
What’s next
A forensic scientist from the Massachusetts State Police Crime Lab is expected to resume testimony Thursday.
Jurors may also see text messages sent on New Year’s Eve between Ana Walshe and a man she was reportedly seeing.
