Brian Walshe, 47, is accused of killing his wife Ana Walshe, 39, on New Year's Eve. Walshe has been in jail since January 8th and was arrested on charges of misleading investigators. Now he is also charged with murder, and disinterring a body.

The prosecution claims that Brian wanted to end his marriage, but elected to kill his wife instead of filing for divorce. He allegedly beat her to death and dismembered the body to dispose of it. The evidence against him is extensive and damning, with none more so than his Google search history beginning at 4:55 am on New Year's day. This harrowing courtroom video shows that history being read aloud.

This list is just some of the terms Walshe searched:

* How long before a body starts to smell? 

* What does formaldehyde do? 

* How long does DNA last? 

* Can identification be made on partial remains? 

* Dismemberment and the best ways to dispose of a body. 

* How to clean blood from wooden floor. 

* What happens when you put body parts in ammonia? 

* Is it better to put crime scene clothes away or wash them? 

* Hacksaw best tool to dismember. 

* Can you be charged with murder without a body?

Despite the strongly incriminating nature of these searches, Walshe's attorney Tracy Miner claims that the prosecution's evidence is not strong. "In my experience, where, as here, the prosecution leaks so-called evidence to the press before they provide it to me, their case isn’t that strong. When they have a strong case, they give me everything as soon as possible. We shall see what they have and what evidence is admissible in court, where the case will ultimately be decided." Walshe has pleaded not guilty to all three of his charges. 

Ana Walshe was a corporate real estate manager and was reported missing from her job on January 4th. Brian claims that she left home for a work trip to Washington D.C. the morning of New Year's Day, although no evidence of such a trip exists. Instead, her phone's signal remained near the area of their Massachusetts home until January 2nd. 

Prosecutors allege that Brian disposed of parts of Ana's body at different trash collection points, and there is surveillance footage of his car, and a figure matching his description to support this. Police also recovered trash he supposedly discarded at his mother's house, containing blood stains, a hacksaw, hatchet, gloves, towels, and more. They also included Ana's vaccination card and one of her purses. 

Perhaps even more damning, blood stains were found in Brian's car and basement, along with a bloody knife. Brian also has an extensive January 2nd purchase list totaling over $450, including a Tyvek suit, hatchet, mops, rugs, trash bags, baking soda, and more. 

Were this evidence not enough, there is no squeaky clean personal record for Brian to hide behind. Brian's father removed him from his Last Will and Testament, and a friend of his father described Brian as, "not only a sociopath but also a very angry and physically violent person."

Many families have already reached out to help support the three children left behind by this tragedy, and here's to hoping justice is quickly served for Ana's murder.
