"Here's the thing guys, we were barking up the wrong tree all along. That's why we were never able to approach the killer. We always thought that Adhik Rodriguez died instantly after he was shot. After all, he was shot three times. But let's suppose, what if he didn't die immediately after being shot ?"
Max took a deep breath and said excitedly,
"Let me paint the picture for you guys. After Bucky deliberately triggered the security alarm, causing Adhik Rodriguez to run to the panic room along with Jimmy, he also entered the house after them. After all, as his assistant, he must have a key to the house.
Subsequently, he must have followed Adhik Rodriguez and snatched his gun after a scuffle. "
"Seeing the gun in Bucky's hands, Adhik Rodriguez must have been scared. In fear, Adhik Rodriguez enters the panic room anxiously. But just at this moment, Bucky shoots him in the back from outside, followed by two more shots in the chest.
