The husband of a Massachusetts woman who's been missing since New Year’s Day conducted a series of gruesome internet searches about ways dismember and

and who has already charged with misleading investigators in the search for the mother of three, was arraigned in court Wednesday on charges of murder transport of a body.

Ana Walshe, 39, was last seen more than two weeks ago, on New Year's Day, and was reported missing by her employer a few days later. Her body has not been found.

Brian Walshe, 47, was escorted just after 8 a.m. into Quincy District Court to be arraigned on the new charges. A not guilty plea was entered on his behalf and he was held without bail.

During his murder arraignment, Norfolk Assistant District Attorney Lynn Beland outlined a series of grisly Google searches allegedly conducted by Brian Walshe 

in the days after the woman's disappearance that included queries about disposing of a body, dismembering a body, body decomposition,

how to mask the smell of a decomposing body and how to clean up blood. "It is believed that Brian Walshe dismembered Ana Walshe and discarded her body," Beland said.

Beland said it's believed that Ana Walshe's remains ended up at multiple transfer stations across eastern Massachusetts, and some were destroyed

or incinerated before investigators searched those sites. But multiple plastic bags containing DNA and other evidence were located 

in a dumpster from Swampscott and searched at a Peabody transfer station, Beland said.
