That said, online discussions have circulated a dramatic narrative: investigators allegedly re-examined trace DNA evidence collected from multiple teenagers who were present on a cruise linked to the broader case. According to these rumors, an initial arrest focused on Anna’s stepbrother, Timothy, was later complicated by forensic inconsistencies that supposedly suggested the involvement of another unidentified male. Some posts even claim investigators quietly expanded their suspect pool after discovering mixed genetic profiles on personal belongings and shared cabin spaces.

However, no official FBI statement, court filing, or reputable news outlet has confirmed these developments. Legal experts emphasize that DNA interpretation in confined environments—such as cruises with shared facilities—can easily lead to contamination or misleading preliminary results if taken out of context.

Until verified evidence emerges in court or through official investigative releases, the “second killer” theory remains speculative and unsubstantiated.
