Ms. I., client of the Aaden Detective Agency Cologne, is a woman with a high income, though not wealthy in the usual sense of the term. She owned a pleasant house in Cologne-Lindenthal with stylish furnishings, a small city car, and three valuable pieces of jewelry whose resale value had been estimated at over 20,000 € a few years earlier. Except for the car, however, Ms. I. had not purchased these valuables herself but had inherited them. Instead of expensive status symbols, she preferred to invest her income in services that would make her life easier. However, one of these services had the exact opposite effect, which led to the engagement of our detectives from Cologne.
Two service providers regularly entered Ms. I.’s home: a cleaning worker, colloquially referred to as a house cleaner, who sometimes brought her husband along to work, and a woman who occasionally helped Ms. I. transport packages, as the client of the Aaden Detective Agency Cologne ran a small mail-order business on the side. She generally got along well with both individuals during the few conversations they had and trusted them to some extent. However, when one day her inherited jewelry disappeared from a box on the upper floor, she was quickly able to narrow down the circle of suspects to these few individuals. Ms. I. met with the private detectives of the Aaden Detective Agency Cologne and received advice on options for identifying the perpetrator and recovering the stolen property. Our detectives recommended setting a so-called theft trap. As Ms. I. suspected the cleaning worker more than the package assistant, she and the Aaden Detective Agency Cologne agreed to set the trap during the cleaning worker’s next visit to the client’s home.
As a first step, an investigator from the Aaden Detective Agency Cologne conducted an on-site inspection of Ms. I.’s house in order to determine which type of theft trap would be most suitable and where it could be placed. Ultimately, it was decided to set a relatively simple trap: an inexpensive imitation of a luxury brand watch, recognizable as such only to experts, would be placed within the field of view of a hidden camera. If the cleaning worker were to steal the imitation, this would very likely serve as sufficiently clear evidence to also prove responsibility for the initial theft. Due to the value in dispute and the use in private premises, the temporary installation of covert video surveillance equipment by our detectives from Cologne is considered justified in this case.

An imitation of a similar brand watch (albeit for women) served as bait for identifying the perpetrator by the Aaden detectives from Cologne.
As a test, the Aaden Detective Agency Cologne installed the camera one day before the cleaning worker’s next visit – everything functioned flawlessly. On the decisive day, two surveillance operatives positioned themselves with two vehicles at the two exit routes from the residence in order to follow the cleaning worker to her place of residence after work if necessary, as this address was unknown to Ms. I. (the cleaning services were performed on a contract basis against receipts; Ms. I. had never requested the address and only knew the family name). One of the observing detectives from Cologne had set up a radio connection from the hidden camera to his tablet and was therefore able to monitor live whether the watch would be stolen. The suspect usually arrived at the workplace by public transportation, but on this day she appeared with her husband, who drove her to work and assisted with the cleaning. However, that was not his only activity in the house: he also examined the placed watch for a few seconds before slipping it into his pocket.
After completing the cleaning work, the perpetrator and his wife got into their car and drove off, followed by our private detectives from Cologne. The journey led to a nearby single-family home of noticeably upscale style. The detectives considered it highly unlikely that the subjects lived there; rather, it was probably another location where they performed cleaning work. Accordingly, the surveillance operatives of the Aaden Detective Agency Cologne waited until the work there was also completed and the subjects would proceed to their next destination. This then turned out to be their actual residence, as the known family name was found on the doorbell and mailbox.
Once this had been verified and the Aaden detectives had consulted with Ms. I., they rang the doorbell to confront the subjects with the evidence. The victim and our investigators sincerely hoped that the stolen jewelry had not yet been sold to fences. The perpetrator initially reacted very irritably to the statements of our Cologne detectives and argued loudly. This, in turn, prompted his wife, to whom we explained the situation and pointed out that there would be criminal consequences if the stolen goods were not immediately handed over. She appeared completely shocked, and her anger was clearly directed at her thieving husband, even though the investigators could not understand what she was shouting at him due to language barriers. Ultimately, he became very subdued and retrieved all of Ms. I.’s stolen jewelry from a hiding place in the apartment. The detectives of the Aaden Detective Agency Cologne also prepared a handover protocol and an acknowledgment of guilt, both of which were signed by the perpetrator, before taking their leave. Both documents were handed over to Ms. I. for her use at her own discretion. Incidentally, the counterfeit watch was anonymously handed over to the authorities after the case was concluded.
