The contain-and-callout option didn't seem to be working. No answer on the phone. There was reluctance to use a bullhorn/haler. This noise would wake the neighborhood, bringing out on-lookers and forcing patrol to deal with an additional problem.
Also rejected was the idea of using the key to open the front door and turning a police dog loose inside the residence. The looks of disbelief on the faces of the other command personnel in the CP caused the sergeant who made the suggestion to quickly retract it. Yep, great thought. Let the K-9 tear up anybody they encounter, then the operators can stay safe and pick up the pieces. Even a dog on a long lead was extreme when considering the intell the commander had at the time.
The detectives and patrol cops had re-interviewed the daughter, son-in-law and other neighbors who were at the CP. The only negative comment was from the daughter who said, "Well, dad sometimes raises his voice to mom."
The commander decided that an entry team of 10 operators would make a controlled entry through the front door using the key obtained from the daughter.
At approximately 4 a.m., the entry team made its approach to the front from a neighboring backyard. Some of the perimeter personnel were assigned to over-watch with the snipers. They were instructed to also watch for any threats in the houses and yards that the entry had passed enroute to the target. Ambush, however unlikely, was a consideration. The team stacked off the small porch as best they could, and all involved personnel were advised entry was in progress. The door opened into a split-level home. From the foyer, a team sergeant shouted, "Police, anyone in here, show yourself with your hands up."
