  • Rosemont hotel: There’s no video of Kenneka Jenkins walking into freezer

Surveillance video of Kenneka Jenkins walking into an industrial freezer at the Crowne Plaza Chicago O’Hare Hotel & Conference Center does not exist, a hotel spokesman told CBS Chicago. There is no surveillance camera that films the entrance to the industrial freezer where 19-year-old Jenkins was found dead September 10. “I want to see her literally, actually walking into this freezer,” her mother, Tereasa Martin, said last week. Social media has exploded with theories about foul play, partially fueled by a Facebook Live video posted by one of Jenkins’s friends.  [CBS Chicago] [Tribune]
