This last Sunday, a local man murdered his wife and then ran away. Emulating Boston, they locked down the neighborhood to find one man:
[Victim] was found dead in the couple’s home in the Governors Club neighborhood just before 6:00 p.m. on Sunday. [Suspect] was not at the scene when police arrived. An extensive overnight search for him came to and end shortly after 6:00 a.m. on Monday when [Suspect] was taken into custody without incident.
During the search, police went door-to-door in the neighborhood and would not allow anyone in or out.
For 12 hours, no one was allowed to enter or leave while police went door to door searching for a man who was not in the area being searched. (He returned home thinking police had left)
No word on whether the locals used FLIR, MRAPs, or the National Guard.
