Officers and K-9 units searched the wooded area behind the Charles River Apartments on Sunday night and Monday morning as police looked into the disappearance of a Waltham man. 

Thomas Astore, a 57-year-old white male, went missing on Sunday. According to a tweet from the Waltham Police Department, his vehicle was found parked in the area of Sawyer Road, the road that leads down to the cemetery near the Charles River Apartments. Astore has gray hair and is 5 feet 8 inches tall and 180 lbs, per the alert. He was last seen wearing a gold sweater, brown jacket and blue jeans, according to the Waltham Police Department’s tweet. 

Waltham Police also advised residents to avoid approaching Astore if they see him. “Do not approach, call Waltham Dispatch at 911,” the tweet read. 

Director of Public Safety Ed Callahan confirmed in an email to the Justice that the police presence near the Charles River Apartments was related to the missing person. 

Amanda Drapcho, the area coordinator for the Charles River Apartments, emailed residents to notify them of the police presence on Charles River Road. “This has nothing to do with Brandeis University and there [is] no reason for concern,” she wrote. 

Waltham handled its most recent missing-persons incident a few weeks ago, when Keisha Cruz was found safe on Jan. 23 after going missing. The 22-year-old Cruz went missing from a group home on Jan. 21, and the Waltham Police reported at the time that she had limited vision and hearing and was possibly suicidal.
