Can we draw the following hypothesis from the context?

Context:

Prosecutors, who stated their intent on Sunday to seize bonds and cash from Madoff, filed another notice on Tuesday listing assets that they intend to seize, among them "various pieces of jewelry owned or held in the name of Ruth Madoff valued at approximately $2,624,340," and "approximately 35 sets of watches and cufflinks owned by Bernard Madoff," as well as $31.5 million in loans made to Madoff's sons.

Hypothesis: The Madoff's acquired all of their watches and jewelry by illegal means.
It's impossible to say
