It looked to me as if the shooter was using a suppressed Ruger MKIV with subsonic ammo that did not have enough power to work the semiautomatic action and he had to manually recycle the bolt between shots.

good point
If so there should be at least two casings in addition to three cartridges on the ground. Wonder what the other two had written on them, if anything?
The weapon looks like a welrod. A welrod needs to be chambered manually after each shot.
The shooter grasped the top of the handgun with the heel of his hand and four fingers to rack the slide, common with a handgun that has a floating barrel and a slide.
The Ruger Mark I-IV series all have a fixed barrel attached to the fixed Receiver. The Bolt moves within the fixed Receiver. Since only the two tabs on the rear of the Bolt are exposed, to cycle the Bolt, one would grasp the two tabs from the rear of the Receiver with the thumb and side of the pointer finger.

That seems to be the opinion of many in regards to the gun type. Although, he apparently failed to test his equipment before-hand. That was a mistake.
ABC News reported Wednesday night that the words “deny,” “defend” and “depose” were written on the casings found at the scene, citing law enforcement sources.
So says a tweet. I will look for the original source at ABC.
