An investigation is underway after Delaware County Sheriff Siddiq Kamara received a racist voicemail with graphic threats. The Delaware County Sheriff's Office released the voicemail Monday that was left on Kamara's official telephone line over the weekend. Detectives at the Delaware County Criminal Investigation Division have launched an investigation into the voicemail. Kamara said in a statement that he won't let the threat deter his work. "If anything, this has strengthened my resolve and reaffirmed why our mission matters," Kamara said in a statement in part. #delawarecounty #delco
