(CNN) — Prosecutors at Brian Walshe’s murder trial continued Tuesday to present evidence they say proves he killed his wife around New Year’s Day 2023 at their Massachusetts home.

On the seventh day of witness testimony, the jury heard about DNA testing that found Ana Walshe, a corporate real estate manager, was a statistical match for DNA recovered on items – including a bloody rug and bath towel – that prosecutors say her husband threw away trying to cover up her killing.

The panel also saw surveillance footage of Walshe buying new rugs and bath towels at a home store in the days after his wife’s death.

Before the trial, Walshe pleaded guilty to illegally disposing of his wife’s body and misleading police after her death, but the jury doesn’t know that. He maintains he did not kill her.

During opening statements, his attorney told the panel Walshe panicked when he found his wife inexplicably dead in their bed in the early hours of New Year’s Day in 2023 and then lied to police because he thought no one would believe he wasn’t responsible for her death.

Wednesday, the jury is expected to hear from Ana Walshe’s former boss, who spent New Year’s Eve at the Walshes’ home and was the last person other than her husband known to have seen her alive.

DNA testing links Ana Walshe to blood stains on items recovered in dumpster searches

Testing found Ana Walshe was a statistical match for DNA recovered on items investigators retrieved from dumpsters near the apartment complex where Brian Walshe’s mother lived. Prosecutors say Brian Walshe threw away the items January 5, 2023, after killing his wife.

A forensic scientist from the Massachusetts State Police Crime Laboratory, Saman Saleem, testified Tuesday that Ana Walshe was a statistical match for DNA found on a blood-stained white towel, a blood stain on the blade of a hacksaw, a blood-stained piece of carpet, a clump of hair and a piece of human tissue found in the garbage bags.

Ana Walshe’s body has not been found, so this is closest thing to finding her remains the jury has heard about so far.
