The death of a 19-year-old, whose body was found inside a Chicago area hotel's walk-in freezer in September, has been ruled an accident, the Cook County Medical Examiner's Office said in a statement.
Although Kenneka Jenkins died of hypothermia, the medical examiner's office released a statement saying alcohol and a drug that's used to treat epilepsy and migraines were "significant contributing factors," the Chicago Tribune reports.
The teen's body wasn't found until nearly 24 hours after she initially disappeared from a party on the ninth floor of the Crowne Plaza in Rosemont, which is a Chicago suburb.
Days after her death, authorities released surveillance video of Jenkins wandering through the kitchen around 1 a.m. on Sept. 10.
The medical examiner's office performed comprehensive toxicology tests to determine whether "date rape drugs" were in her system, but none were found.
The office did, however, say that the combination of alcohol and the medication in Jenkins' system could have caused "impaired memory and concentration, poor coordination, confusion and impaired judgement," the Tribune reports.
Rosemont police released a statement Friday, saying that there is currently no sign of foul play. Still, authorities are searching for at least two out of 36 people who attended that same party.
One of those two people is Shaniqua Watkins, who police say used a stolen credit card.
In addition, authorities told the Tribune they are still waiting for the surveillance video to be "enhanced for further examination" before the investigation is concluded.
