Breitwieser and Anne-Catherine are aware that the police are trying to find them due to local news reports.
Breitwieser intentionally leaves painting frames in conspicuous places in museums as a taunt to authorities, calling it his "calling card".
Police tend to assume that stolen artwork ends up being sold on the black market, ransomed back to their owners, or used as currency in criminal dealings.
Law enforcement tries to break up these illegal activities by identifying and infiltrating the transactions of stolen art.
Art crime units focus on recovering the stolen artwork, even more than arresting the criminals involved.
Despite the difficulties and risks, some law enforcement agents go undercover to get closer to the criminal organizations involved in art theft.
It's rare for a thief to simply keep stolen art for personal enjoyment, as the financial value of such items is usually their primary attraction for criminals.
Breitwieser believes he can allude authorities by stealing in a random, unpredictable pattern.
