A 42-year-old woman died following a Tuesday morning traffic stop in Waterloo that resulted in multiple arrests on drug and burglary charges.

The traffic stop occurred shortly after 8 a.m. in the 900 block of North Market Street off Route 3. Waterloo police said a U-Haul truck was stopped for a traffic violation and three occupants were arrested on drug charges. Several police vehicles responded to the scene, witnesses said.

During the booking process, the 42-year-old woman appeared to have swallowed a baggie containing an unknown substance. She was transported by ambulance to Memorial Hospital in Belleville at that time, police said.

Upon her release from the hospital, the woman was transported by Waterloo police to the Monroe County Jail.

“Upon arrival at the jail, it was discovered that she was unresponsive and CPR was administered,” a Waterloo police press release states.

The woman was then transported by Monroe County EMS ambulance to Red Bud Regional Hospital, where she was pronounced dead.

Randolph County Coroner Carlos Barbour is investigating her death, police said. Barbour identified the deceased as Amanda Latimer, 42, of Granite City.

Jacklyn McCormack, 30, of Belleville, and Shaun Myers, 38, of Caseyville, have been charged with possession of methamphetamine and burglary. The burglary charge stems from an alleged incident that occurred early Tuesday morning at Fountain Inn, 1912 Fountain Road near Valmeyer.
