Prosecutors Share DNA, Google Searches They Believe Will Lead To Brian Walshe Conviction

Brian Walshe is facing a murder charge in connection to his wife's disappearance, and prosecutors shared some strong evidence they say they have against him during a Jan. 18 arraignment.

Brian Walshe, who has pleaded not guilty to murdering his wife, Ana Walshe, who disappeared on New Year's Day, was mostly stoic as prosecutors read off the evidence they say they have against him, including DNA and troubling Google searches he allegedly made on the day the Massachusetts mother of three disappeared and in the following days.

Investigators have not found the body of the missing woman, but prosecutors shared circumstantial evidence that they believe will be enough to convict Brian Walshe.

Among those findings in trash bags that prosecutors say Brian Walshe was seen taking to various trash compactors were his and her DNA on clothing and a necklace that photos showed Ana Walshe wearing previously.

Prosecutors also read off troubling Google searches that Brian Walshe allegedly made on his son's iPad. Among those were the following:

—How long before a body starts to smell

—How to stop a body from decomposing

—Can you throw away body parts

—How long does DNA last

—Can an identification be made on partial remains

—Dismemberment and the best way to dispose of them

—How to clean blood from a wooden floor

—Can you be charged with murder with no body

—Can you identify a body with broken teeth

Prosecutors requested that Brian Walshe be held without bail, and the judge accepted that request.

Brian Walshe had already been in federal prison awaiting sentencing for an art fraud scheme.
