The officer whose bodycam we are watching is Officer Nunes (you can see how it matches his report in the MPD doc releases #3. He was only 22...
Dylan did good job of describing what she saw to Nunes. I was impressed at how she held it together well enough to answer his questions and keep answering them.
I know some of HJ's reaction is calm reaction is shock....but also...I think he is a person who snaps right into a practical, take care of a situation mode the moment he senses a crisis. He could have waited on Emily to get dressed and walk over with her...he didn't...he went straight over himself...he went right in the house....and once he knew he got BF and DM out and got them calling the cops while he went to get a knife to make sure the murderer wasn't still there. Then he checked Xana's pulse just to be thorough....because while he knew she and Ethan were dead, he had to check if there was any tiny chance she was still alive and he could help.....and if Xana was cold, he knew both of them were long gone. That poor poor boy.
Those poor poor kids.
