In the search warrant return (last few pages) there is a box on the right hand side that indicates which items were sent to the lab. I can see the gun, keepsake box cartridge and the carpet cutting from the car were indicated to be sent to the lab.
I’m not sure about warrants surrounding LISK. I haven’t read any of the court documents so I’m not sure what they collected from “public trash” vs what was in the warrant. I totally just assumed they got a warrant for the wife’s hair for that security. I did learn a lot from LISK about the digital aspect, how much information the FBI/LE can recover from old computers, phones, geofencing, deleted items etc. it’s been incredible to see what they’re able to recover from 20+ years ago. We need that level of forensic investigation over here.
