The Madison County Sheriff's Office is investigating the death of a Worchester, N.Y., woman at a Highland convenience store that may be drug-related, according to Sheriff Robert Hertz.
The woman is identified as 25-year-old Angela K. Lamar.
The sheriff's office and Highland Ambulance Services responded to reports of an unresponsive female at 1 a.m. Sunday to CC Food Mart, 3410 George St. in Highland.
Lamar was found in the women's restroom. She was transported to St. Joseph's Hospital in Highland, where a Madison County Deputy Coroner pronounced her dead, according to police.
Investigators seized a syringe and heroin-filled capsules during the investigation. An autopsy was conducted, but an official cause of death is pending toxicological examinations.
Police say Lamar was traveling through Illinois with her boyfriend, who is a truck driver.
