Authorities are investigating a series of overdoses in northeast Mississippi that led to two deaths.

Booneville Police Chief Michael Ramey said Tuesday that two people had died and three more were hospitalized after taking illegal drugs containing fentanyl.

The Mississippi Bureau of Narcotics, which is assisting the investigation, says the overdoses took place Monday.

Ramey says the drugs came in pill and powder form and tested positive for fentanyl at the state Crime Lab. Police are warning people not to touch any suspected drugs.

Prentiss County Coroner Greg Sparks says the two deaths did not happen at the same location but are believed to be connected. WTVA-TV reports one of the people who died was a woman named Veronica Kimble. The second person’s name hasn’t been released.
