Police investigating the death of a 19-year-old Chicago woman who was found dead in a suburban hotel freezer say at least 12 people were “involved in some way.”

CBS 2 reports that police interviewed the twelve people in regards to Kenneka Jenkins’ death after she was found dead in a walk-in freezer at the Crowne Plaza Chicago O’Hare Hotel & Conference Center in Rosemont, Illinois, around 12:30 a.m. Sunday.

After mounting pressure from the public, police released a statement Wednesday on the status of their investigation. Police are conducting “an active death investigation” and detectives have been in consistent contact with Tereasa Martin, Jenkins’ mother, the Rosemont Public Safety Department said.

Dozens of protesters demanded police provide more information about the teen’s death on Wednesday.

Investigators are reviewing video from 47 hotel cameras as well as “certain videos related to this investigation.”

Police are also examining a Facebook Live video that appeared to show Jenkins sitting on a bed in a hotel room with others on the 9th floor.

Eight of the twelve people who spoke with police regarding Jenkins’ death were at the hotel Friday night or early Saturday morning. Police are attempting to locate and interview four other people who were also present that night.

Jenkins reportedly went to a party at the hotel with friends Friday night after borrowing her mother’s car. At 4:30 a.m. Saturday, her friends called her family and told them she was missing.

Jenkins’ mother filed a police report, but said she had to wait in order to do so. Hotel staff then conducted an 11-hour search and found Jenkins’ body in the freezer.

Results of an autopsy conducted by the Cook County Medical Examiner’s Office are pending.

“We extend our deepest condolences to the family and friends of Kenneka Jenkins,” the department said.
