As reported by Minnesota's Unsolved Cases, it is also possible that Swanson was either abducted or involved in a hit and run, and the driver panicked and disposed of his body. However, there is simply no evidence proving either theory.

Annette and Brian Swanson believe their son's disappearance may have been solved if law enforcement had begun their investigation immediately after they reported him missing. 

As reported by FindLaw, states do not generally require a waiting period for reporting a child or an adult missing, However, priority is often given to cases involving young children, people who are mentally or physically impaired, or cases where foul play is evident.

As reported by The True Crime Files, the Swansons proposed a law in their son's name, which would "require law enforcement to take a missing persons report without delay after notification of someone missing under dangerous circumstances, no matter the missing person's age; immediately conduct a preliminary investigation to determine if the person is missing, and whether the person is endangered; and promptly notify all other law enforcement agencies of the situation."

Brandon's Law, which was sponsored by former House Minority Leader Marty Seifert and Senator Dennis Frederickson, was signed into law by Minnesota's then-Governor, Tim Pawlenty, on May 7, 2009. The law officially went into effect on July 1, 2009.
