The Boston attorney who was found stabbed to death on his houseboat was wrapped and weighted down, a prosecutor said.

A Boston woman charged with a grisly murder on a houseboat claimed during a Friday arraignment she was totally unaware of the death, even as police say the woman was seen running and moving things near the bloodied body inside the boat just before her arrest.

A prosecutor revealed in court on Friday that an officer found the victim’s body “wrapped in a white and blue covering, secured with duct tape and affixed with weights."
