A Massachusetts man has been found guilty of murdering his wife, who has never been found after she disappeared nearly three years ago. Brian Walshe was convicted of first-degree murder Monday after pleading guilty last month to lesser charges of misleading police and illegally disposing of her body. Investigators relied on online searches Walshe made about dismemberment and disposing of a body. Surveillance also showed a man resembling him throwing heavy trash bags into a dumpster. Prosecutors showed photos of many items recovered that were connected to Ana Walshe, including her vaccination card.
