It takes time to do do a thorough investigation. Camera footage will be reviewed, interviews will be done with officers involved, witnesses, family and friends. Autopsy will be completed as part of the routine investigation. You will just have to understand that this information wont be shared until the investigation is finished. If this incident involved my family I would want the investigation to be done completely and once it is completed then it can be become public information. Let the cops do their jobs. This case is barely  24 hours old. It is NOT TV or a reality show. It is real life with real people who deserve respect and compassion.
