On April 28, the SWAT team executed a search warrant at Rideau's home that, along with the suspect's arrest, yielded  five ounces of crystal methamphetamine, half an ounce of marijuana, half an ounce of “crack” cocaine, various prescription pills, over 10 cell phones, U.S. currency derived from the drug sales and a 2005 Nissan Altima used to traffic and distribute illegal narcotics.

In another narcotics investigation, the sheriff's office was tipped off by concerned residents and business owners in the Grand Coteau area.
