"All indications we have got that I can't tell you point in the direction that Madeleine is dead.
"We got things we cannot communicate that speak for the theory that Madeleine is dead, even if I have to admit that we don't have the body."

Thanks. That could refer to the alleged confession though as they are not going to tell us what was said in the alleged confession. It would still remain a confession made out of the police station and relayed by a 3rd party not the suspect.
I found a document on German Trials, page 19 has info on the 'pre trial investigation stage'.
The bolded bit is their emphasis
'At the end of the investigation, an indictment or termination order will be issued by the prosecutor and sent to the competent court.........The suspect is to be indicted whenever there are
reasonable grounds to believe he or she might be convicted at the end of a trial
....The bill of indictment shall indicate the criminal offence with which the accused is charged, the time and place of commission.....'
