Witnesses, POI, suspects. LE differentiating between the 3. Have to be able to PROVE with EVIDENCE. All of the families are of course shocked. These 3 plus the original 2. Plus Project Houston. Very thankful for their help and understanding. It's been very draining on all the investigators. 12 investigators, plus K9, forensics. They've never seen anything like this. Very tiring and very draining.
