QUINCY, Mass. — Brian Walshe, the Massachusetts man accused of killing his real estate executive wife, Ana, used his son’s iPad to conduct well over a dozen Google searches in the days after her alleged disappearance, prosecutors said Wednesday. 

"At 4:55 a.m. on January 1, he searched, ‘How long before a body starts to smell?’" Commonwealth attorney Lynn Beland told the court on Wednesday during Walshe’s arraignment on upgraded charges. "At 4:58 a.m., ‘How to stop a body from decomposing.’" 

The Google searches allegedly continued for days. Walshe, 47, was charged Wednesday with murdering 39-year-old Ana Walshe and then disinterring and improperly transporting her body, officials have said. Ana, who shares three sons with Brian, was last seen in the early morning hours of Jan. 1, after ringing in the New Year with Brian and the couple’s friend.

Walshe's attorney, Tracy Miner, spoke only briefly during Wednesday's arraignment, but did not contest the prosecutors' request for no bail. She did not speak to the allegations against her client, but she released a statement on Wednesday afternoon.

"It is easy to charge a crime and even easier to say a person committed that crime," she said. "It is a much more difficult thing to prove it, which we will see if the prosecution can do. I am not going to comment on the evidence, first because I am going to try this case in the court and not in the media.

"Second, because I haven’t been provided with any evidence by the prosecution. 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.

"Although it is probably fruitless, I ask that you not inundate my office, my home or my cell phone with media requests. I will not be giving any media interviews or comments. I intend to win this case in court, not in the media, which has already tried and convicted Mr. Walshe."
