The press conference didn’t give the public any new information, really, so it’s tempting to be disappointed by it.
However, I didn’t get the impression that the police are struggling to gather evidence or to identify a suspect. I think “we don’t have a suspect” was an outright lie, to not spook the suspect. I think they do have a suspect, and they’re working ‘round the clock to assemble the evidence and plan the arrest.
The police clearly are not asking for the public’s help, nor do they seem concerned that there’s a random murderer the public might be in danger from. I got the impression that the police HAVE a lot of information and knowledge about the Tepe murders but simply can’t share it with the public because it’s premature and it would compromise the case.
Of course, I could be wrong. I can’t really explain why the press conference gave me hope… it’s just a feeling. The police’s job isn’t to keep the public informed about all the details of a case just to satisfy our curiosity, or to confirm or deny internet rumors. Their job is to identify and catch a murderer and document the evidence in a way that can lead to his conviction in court. Withholding information from the public can be a crucial part of that, and/or giving the public partial or even misleading information. It might make it easier for them to apprehend the suspect if he sleeps well at night because he heard the police say on TV that they don’t have a suspect!
