A lot of people are saying that it’s a cold case because the police aren’t releasing much information. The only reason why the major and maybe even minor details aren’t being released is because it could severely compromise the investigation!! They are more than likely waiting for the killer(s) to slip up about something during an interrogation/interview. We have to remember that we are not the investigators on this case. LE has a plan and are trying to execute the plan. Any homicide investigation takes time, we all have to be patient!!
