As I recall, the appeal was only in connection with a phone call allegedly received by Christian B
These are the things the BKA appealed to the public for information on, taken from their website:
- Can you provide information on the vehicles used by the suspect and/or have you seen the vehicles in the beginning of May 2007?
- Do you know where these vehicles were parked in the aforementioned time period?
- Can you provide information on the above-mentioned telephone numbers and/or the persons using these numbers in May 2007?
- Can you provide information on the houses and rooms in the photographs or on other points of contact?
- Did you also stay in the Algarve in the beginning of May 2007 and do you still have image material, such as holiday photographs and videos, from that time?
- Did you have contact with persons who have links to the vehicles, buildings and telephone numbers shown?
- Can you provide information on their whereabouts in the beginning of May 2007?
- Have you yourself possibly been the victim of an offence committed by this person?
- Furthermore, there is reason to assume that there are other persons, apart from the suspect, who have concrete knowledge of the course of the crime and maybe also of the place where the body was left. We explicitly ask these persons to contact us and provide information.
