BERLIN (AP) -- The Latest on investigation of truck rampage in Berlin Christmas market (all times local):
The head of Germany's Federal Criminal Police Office says he cannot rule out that suspects involved in the truck attack on a Berlin Christmas market could still be at large.
Holger Muench told reporters Tuesday that authorities are still not positive the suspect they have in custody was the driver of the truck, that they have not yet found a pistol believed used to kill the truck's passenger, and that it is not known overall how people were involved.
For those reasons, he says, we are "naturally on high alert and are investigating in all directions."
He says six of the 12 people killed have been identified and are all Germans, but he does not yet know whether the other six are as well.

Peter Frank also told reporters Tuesday it's not entirely clear whether there was one perpetrator or more. He says the suspect in custody "may not have been the perpetrator or belong to the group of perpetrators."
Frank says the method used in the rampage was reminiscent of July's truck attack in Nice, France and of the "modus operandi" used by Islamic extremist groups.
