Kenneka Jenkins, 19-year-old Chicago teen, was found dead in a walk-in freezer at the Crowne Plaza Hotel in the Chicago suburb last Sunday.

Protesters gathered once again on Monday evening to call for federal intervention in the death investigation, due to distrust in local law enforcement officials.

Investigators concluded that no foul play was involved regarding Kenneka Jenkin’s death. On Friday, they released video surveillance footage showing Kenneka Jenkins wandering around a restricted area of the hotel, but there was no footage of her actually entering the walk-in freezer where she was found.

“This investigation has been and remains the utmost priority for us,” Rosemont Police Chief Donald E. Stephens III said in the statement send to the Chicago SunTimes. “Throughout this investigation we have used any and all outside agencies necessary to complete a thorough investigation and will continue to do so as needed.”

Chicago activist, Jedidiah Brown, said he was extremely skeptical of the investigation’s integrity, referring to it as “just strange.”

“Until the mom has peace and Kenneka has true justice, we’re going to keep on the fight.”

Rosemont police said that there was “no credible evidence at this point” that would prompt police to reclassify Kenneka Jenkins’ death as a homicide.

An initial autopsy was inconclusive, and further study is pending.

Kenneka Jenkins’ sister and mother, Tereasa Martin, were among the more than 100 attendees of last night’s protest.

Officials associated with the Crowne Plaza have said that they have offered Jenkins’ mother the opportunity to view all 36 hours of surveillance footage from the hotel. They said the family has yet to respond to the offer.

“We have not heard from the family or their representatives,” hotel spokesman Glenn Harston told the Chicago Sun-Times on Monday.
