Amid pressure from Kenneka Jenkins family, Police release new information involving death probe.

Rosemont officials released some new details late Wednesday about their investigation into the death of Kenneka Jenkins and said they will share hotel surveillance video with her mother.

The developments came as members of Jenkins' family and others protested in front of the hotel where the Chicago teen was found dead Sunday after attending a party there.

Earlier Wednesday, Rosemont Mayor Bradley Stephens said local police are working with outside agencies to investigate Jenkins' death but that fevered online guesswork about the case is hindering the probe.

"It's unfortunate that some of that stuff's convoluting the investigation because all those leads have got to be followed up on," he said after his annual state of the village address to the Rosemont Chamber of Commerce.

"As I'm sure you've seen, there's a lot of different, conflicting speculation out there, so (police) are doing their best to come to a quick resolution, obviously. I think everybody wants to know what happened."

Jenkins, 19, was attending a party in a room of the Crowne Plaza Chicago O'Hare Hotel & Conference Center when she went missing early Saturday. Her family arrived to look for her a few hours later but said hotel staff and village police didn't join the search until the afternoon.

Jenkins' body was eventually found in a walk-in freezer in a vacant part of the hotel, authorities said. She was pronounced dead just before 1 a.m. Sunday.

Rosemont spokesman Gary Mack said police plan to show surveillance video from the hotel to Jenkins' mother, Tereasa Martin, on Thursday, but will not release it to the public until the investigation is finished — a resolution that could be weeks away.

"We're trying to be as understanding as we can to the mom and to be as compassionate as we can," he said. "Now that our detectives have had the chance to look at it, we're hopeful it will be helpful to her."

Mack would not describe the contents of the video, and officials continue to say little about what they've learned about the circumstances surrounding Jenkins' death or the eventual discovery of her body.
