On the evening of July 26, 2017, the body of 64-year-old Rex Mack Olsen was found near a dumpster behind the CVS pharmacy in Warrenton, Virginia, where he worked as the store manager. Investigators determined Olsen had been fatally shot in the head and face and treated the death as a homicide.

Suspicion focused on Bernard Duse Jr., the assistant manager at the same CVS. Cell tower data placed Olsen’s and Duse’s phones traveling together after the time of the killing, heading toward Duse’s residence. A DNA mixture recovered from Olsen’s pants pocket, where he kept his cellphone, contained DNA from both men. Duse was arrested and charged with first-degree murder; his trial began in the summer of 2018 and the jury returned a guilty verdict on August 3, 2018, recommending a life sentence.

If anyone knew Olsen, worked with him at that CVS, or has information about what happened that night, please share what is known.
