Closing arguments are expected to be delivered Friday in the murder trial of Brian Walshe, a father of three accused of killing and dismembering his wife.

The Massachusetts man is accused of killing his wife, 39-year-old Ana Walshe, around New Year’s Day in 2023. He pleaded guilty last month, ahead of the trial, to lying to police following her disappearance and improperly disposing of her body, though he denies that he killed his wife and has pleaded not guilty to murder. Ana Walshe’s body has not been found.

The defense rested on Thursday without calling any witnesses. Judge Diane Freniere noted in court on Thursday that it appeared that Brian Walshe would testify in his defense, based on the defense’s opening statement. Though he ultimately waived his right.

During the trial’s opening statements last week, defense attorneys said that Brian Walshe found his wife dead in bed on New Year’s Day in 2023 and then panicked and lied to police as they investigated her disappearance — but maintained he did not kill her.

Prosecutors allege Brian Walshe killed and dismembered his wife, then disposed of her remains in dumpsters. The internet history on his devices on Jan. 1, 2023, included searches such as “best way to dispose of a body,” “how long for someone to be missing to inherit,” and “best way to dispose of body parts after a murder,” prosecutors said.

Evidence presented during the two-week trial included surveillance footage of a man believed to be Brian Walshe buying tools and other supplies at a Lowe’s on Jan. 1, 2023. A receipt showed that items, including a hacksaw, utility knife, hammer, snips, Tyvek suit, shoeguards, rags and cleaning supplies totaling $462 were purchased with cash.

Additional surveillance footage presented in court showed someone throwing out trash bags at dumpsters on multiple days in early January.

Several blood-stained items recovered from dumpsters by investigators — including a hacksaw, a piece of rug, a towel, hairs and an unknown tissue — were linked to Ana Walshe through DNA testing, a forensic scientist from the Massachusetts State Police Crime Laboratory testified during the trial.

Blood was also found in the basement of the family’s rental home in Cohasset, another forensic scientist with the crime lab testified.

Ana Walshe was reported missing by her employer on Jan. 4, 2023. Brian Walshe told police at the time that she had a “work emergency” at her job in Washington, D.C. and left their Cohasset home on New Year’s Day, according to video of his interview shown in court.

At the time, Brian Walshe and their three children were living in Massachusetts while he was awaiting sentencing in a federal fraud case after pleading guilty to a scheme to sell counterfeit Andy Warhol paintings.

Ahead of the murder trial, Brian Walshe admitted to lying to police amid her disappearance and improperly disposing of her body. His defense said during opening statements that he panicked after finding her dead in bed, calling her death sudden and unexplained.

Jurors heard testimony, including from a D.C. man with whom Ana Walshe was having an affair, that the mother of three was upset about being away from her children so much, and that there was stress in the marriage. The defense maintained that the couple were happy.
