Jimmy followed the SWAT team with his pistol drawn, reaching the corner where the attackers had been. All he saw were some scattered shell casings and magazines, and a bit of blood on the wall—likely where Victoria had been shot.
It had only been Victoria shooting earlier, while Marvin had been loading the magazines. For someone without x-ray vision, it wouldn't have been clear there was a second person. Now with this bloodstain, at least the SWAT could claim later that they had wounded the gunman and start pursuing the injured person, which was a clear clue.
That being said, although they were all elderly, their combat ability appeared to be quite strong—Victoria alone had suppressed the SWAT at both kitchen passages, which wouldn't have been easy for anyone else.
