WATERLOO, Ill. (AP) — Two people arrested during a southern Illinois traffic stop that turned deadly for a third person now face drug charges.

The Belleville News-Democrat reports Jacklyn McCormack of Belleville and Shaun Myers of Caseyville were charged in Monroe County with methamphetamine possession and burglary after Tuesday's traffic stop for a seatbelt violation. Authorities say the burglary occurred Sept. 10 at a Valmeyer motel.

The Associated Press left messages Friday seeking comment from lawyers for McCormack and Myers.

A 40-year-old woman in the truck died at a hospital after police say she swallowed an unknown substance while being questioned. Police say she was initially treated and released from another hospital before being taken to the Monroe County Jail. However, an officer noticed the woman was unresponsive when she arrived at jail.
