The husband of a Massachusetts woman who disappeared around New Years day made more than a dozen google searches including, “how to dispose of a body.”

He also googled,” How to stop a body from decomposing.” in the minutes before he had originally told the police he last saw his wife, prosecutors said Wednesday. Prosecutors presented their evidence against Brian Walshe, 47 years old, in Quincy District Court after issuing a murder warrant Tuesday in the death of his wife Ana Walshe, 39 years old.

He was accused of beating and assaulting his wife. He is also charged with the act of removing the body or remains. This is according to the criminal complaint. He pleaded not guilty to the charges. Early in the morning of Jan. 1, in the hour before telling investigators and Walsh had left their home in the wealthy suburb of Cohasset, he made a disturbing google search from his son’s ipad; “ how long before a body starts to smell.” Later that morning. Brian’s searches included, “ how long does DNA last?”  With enough evidence, they were able to arrest him.
