text:  This is WFMD News. Police in Hagerstown took a man into custody after he allegedly called the Williamsport Retirement Village and threatened to blow it up. Authorities with the Maryland State Fire Marshal's Office say 60-year-old John Calvin Walls left a message on one of the facility's phone lines, and it was an employee who recognized the suspect's voice. Investigators say the voicemail also identified the phone number where the call originated. A thorough search was conducted by K-9 Rosie, a member of the fire marshal's bomb squad.
