Upon arrival to the PD Cpl X, Ofc X, X, and X began holding perimeters’ until K9 Ofc X arrived and then immediately began searching for who everyone assumed would be a second active shooter. Cpl Grollnek arrived at the PD to begin a perimeter until asked to bring the T-Rex to remove possible pinned down victims. As the T-Rex was being mved conduct the request, Cpl Grollnek was advised that Swat would need to be ready for an alternate assignment.
At that time, the Team was advised that they were responding to the suspect’s residence in Ana, TX to conduct an exigent circumstance search of the residence. Once on scene, Cpl Grollnek set up on perimeter with Cpl X and waited for any additional suspects to come outside of the residence as the Swat Team Leader attempted to call out anyone that may be inside.
