From the story in the Globe:

Investigators have found blood and a damaged knife with blood on it in the basement of the Cohasset home where Ana Walshe was living with her husband, Brian R. Walshe, who bought $450 of cleaning supplies before the mother of three was reported missing to authorities, a prosecutor said in court Monday.

During the arraignment of Brian Walshe Monday on a single count of misleading police, Norfolk First Assistant District Attorney Lynn M. Beland described the discoveries police have made since launching a high-profile search for 39-year-old Ana Walshe last week.

Beland said that while executing a search warrant this weekend at the Cohasset home where the couple has been living with their three children, they discovered blood and a damaged knife with blood on it in the basement. Beland did not specify in what way the knife was damaged, nor did she provide details about the bloodstains police found.

Ana Walshe has not been heard from since she left her home around 4 a.m. on New Year’s Day to take a rideshare to Logan International Airport for a flight to Washington, D.C., where she works for a real estate company, family have told police. Investigators have not been able to confirm she took a rideshare, but have determined she did not board a flight from Logan, according to Cohasset police Chief William Quigley.
