(CNN) Authorities have closed the investigation into the death of a young Chicago woman whose body was found in a hotel's walk-in freezer, saying it was accidental and there was no reason to suspect foul play. 
 
 Police in Rosemont, a suburb northwest of Chicago, had been investigating the death of 19-year-old Kenneka Jenkins since her body was found September 10 after she attended a party at the Crowne Plaza Chicago O'Hare Hotel. 
 
 "Our detectives reported no signs of foul play throughout the whole investigation," Chief Donald E. Stephens III with the Rosemont Police Department said in a statement. "There is no evidence that Ms. Jenkins was forced to drink alcohol or consume any narcotics while at the hotel." 
 
 Investigators concluded Jenkin's death was accidental after retracing her path to the cooler that contained the freezer where her body was found, reviewing hours of surveillance video and interviewing most of the people that were at the party that night. 
 
 "There is no evidence that indicates any other conclusion," Stephens said. 
 
 On Friday, police released audio recordings, hours of video surveillance footage and a series of graphic photos showing Jenkins' body on the floor inside the freezer. 
 
 An attorney for Jenkins' family said the photos were disturbing and raised more question about what happened that night, CNN affiliate WBBM-TV reported 
 
 She was alone 
 
 Jenkins' death sparked accusations on social media of foul play. Stephens said Friday that "none were supported by facts." 
 
 "The death of any child is tragic; but the death and circumstances surrounding Ms. Jenkins are especially sad," the police chief said. 
 
 Surveillance video from inside the Crowne Plaza, released by the Rosemont Public Safety Department, showed Jenkins staggering through the hotel's hallways before she disappeared. 
 
 In the footage, Jenkins is first seen walking through the hotel with several unidentified people around 1:13 a.m. on September 9. She appears to be steady. 
 
 But when Jenkins is next sighted exiting an elevator at 3:25 a.m., she is alone and visibly impaired, and staggers out of the elevator, briefly leaning on the wall for support before heading down the hallway. 
 
 The footage showed Jenkins entering a kitchen at approximately 3:32 a.m. but does not show her entering the cooler and freezer, where she was found nearly 24 hours later, because no cameras show the doors directly. 
 
 Police don't believe anyone else came in contact with Jenkins after she entered the kitchen. There is only one entrance into the kitchen and anyone who would have walked toward the freezer would have activated a surveillance camera there, Stephens said. 
 
 Since Jenkins entered the kitchen until her body was discovered only a security guard was seen entering the area. 
 
 "He did not get close to the freezer and was never out of sight of the camera," Stephens said. 
 
 No drugs, signs of trauma 
 
 The Cook County Medical Examiner's office had recently classified Jenkins' death as accidental. 
 
 Her cause of death was hypothermia, the coroner said. 
 
 The medical examiner explained that levels of alcohol higher than the driving limit and topiramate, a drug most commonly used to treat epilepsy and migraines, were also contributing factors. 
 
 "When combined, the effect of either or both drugs is enhanced. Topiramate, like alcohol, can cause dizziness, impaired memory, impaired concentration, poor coordination, confusion and impaired judgment. Central nervous system depression, or impairment, combined with cold exposure can hasten the onset of hypothermia and death," the office said in a released. 
 
 No external or internal trauma as well as "hundreds of drugs of abuse, medications and other chemical compounds" -- along with date-rape drugs -- were found on Jenkins' body, the coroner said. ||||| Rosemont authorities announced late Friday that they have closed the investigation into Kenneka Jenkins’ death and determined it to be accidental, saying there is “no evidence that indicates any other conclusion.” 
 
 However, lawyers for Jenkins’ mother say graphic police photographs taken after Jenkins’ body was found “raise more questions than answers.” 
 
 As part of a release of documents and videos related to the case, Rosemont officials on Friday posted on their website dozens of postmortem photographs of Jenkins taken while her body was still in the hotel freezer where she was found dead. 
 
 Police showed the photographs to Jenkins’ family on Thursday, and Sam Adam Jr., a lawyer for Jenkins’ mother Tereasa Martin, called them “graphic and disturbing images (that) inexplicably show portions of Kenneka’s body exposed.” 
 
 The release from Adam and Martin’s other attorney, Larry Rogers Jr., said the photos were “of a personal, private and indecent nature.” 
 
 Jenkins, 19, was found dead in a Rosemont hotel freezer Sept. 10, about 21 hours after she went missing following a party she attended in a ninth-floor room. 
 
 According to Rosemont police reports, she was found on her side, face down, with her left arm underneath her, her right shoe off and a small cut on her right foot. 
 
 The photographs show that Jenkins was still wearing the jeans and jean jacket shown in surveillance videos of her walking through the hotel before her death, but the shirt beneath her jacket “was pulled up exposing her breasts,” a police report said. 
 
 “Frankly, the photos depicting how Kenneka was found raise more questions about what happened to Kenneka Jenkins than they answer,” Rogers said in the news release. 
 
 Scientists who have studied hypothermia have described a phenomenon known as “paradoxical undressing,” in which people freezing to death remove their clothing. 
 
 “It is concluded that paradoxical undressing might be explained by changes in peripheral vasoconstriction (narrowing of blood vessels supplying the extremities) in the deeply hypothermic person,” scientists wrote in a 1979 journal article. “It represents the last effort of the victim and is followed almost immediately by unconsciousness and death.” 
 
 In announcing in a press release Friday evening that they’ve closed the case, Rosemont police outlined the scope of their investigation and said they found no evidence that Jenkins was the victim of foul play — contrary to the many conspiracy theories that have sprouted on social media. 
 
 “Our detective reported no signs of foul play throughout the whole investigation,” said a statement from Police Chief Donald Stephens III. “There is no evidence that Ms. Jenkins was forced to drink alcohol or consume any narcotics while at the hotel.” 
 
 The statement added: “While there were many theories, rumors and much speculation floating around social media regarding the death of Ms. Jenkins, none were supported with facts. While all leads and theories were investigated by our department, what we have reported throughout the investigation and again, today, are facts.” 
 
 Police said their investigation has generated 135 reports and involved interviews with 44 people, including 30 who were confirmed to have been in the hotel room at some point the night of the party. 
 
 Authorities also viewed dozens of hours of surveillance video; conducted five photo line-ups; performed forensic analyses on four cellphones, including Jenkins’; and submitted three search warrants and four preservation of evidence warrants. 
 
 The police statement said the “death and circumstances surrounding are especially sad.” 
 
 Reached by phone Friday evening, Martin declined to comment on the photographs and the village’s decision to post them on its website. Martin referred calls to her attorneys, who could not immediately be reached. 
 
 In a news release Thursday evening, the lawyers said the death-scene photos were first shown to the family by Rosemont police during a meeting to update the family on the death investigation. 
 
 The lawyers also said Rosemont police had previously denied “numerous requests to review the reports, photographs and videos secured by the department.” 
 
 “Numerous requests for any and all videos and photos showing Ms. Jenkins going into the freezer of her own volition have not been forthcoming, and quite frankly raise more questions than answers as to how and why Ms. Jenkins was found in the condition in which she was located,” the attorneys also said. 
 
 There has been no indication from police that any surveillance video exists that directly shows Jenkins entering the freezer where she was found. But motion-sensor cameras in the kitchen indicate no one else went into the freezer area of the kitchen for days prior to Jenkins entering the kitchen, and no one entered the area after that until the time her body was discovered, according to police reports and surveillance video. 
 
 The Cook County Medical Examiner’s office had already classified Jenkins’ death as accidental and caused by hypothermia, with alcohol intoxication listed as a contributing factor. 
 
 Rosemont police also said in their release Friday that the hotel room where the party took place was booked with a fraudulent credit card and that they believe they have identified two perpetrators who booked the room. Police said they are “affiliated with a gang on the West Side of Chicago whose operations rely heavily on the use of fraudulent credit cards.” 
 
 Police said that case is still ongoing.

 Autopsy and toxicology report on Kenneka Jenkins' death » ||||| Police investigating the death of a young woman found in a Rosemont hotel walk-in freezer are reviewing video on social media that appears to show the victim in a ninth-floor room hours before she disappeared over the weekend. 
 
 Investigators also have been going over surveillance video and questioning potential witnesses, but they have yet to say how 19-year-old Kenneka Jenkins died or why she was in a freezer in a vacant area of the Crowne Plaza Chicago O'Hare Hotel & Conference Center. 
 
 Jenkins' mother, Tereasa Martin, said she last saw her daughter around 11:30 p.m. Friday when she left their West Side home to go to a party. Jenkins' sister last spoke with her around 1:30 a.m. Saturday, close to the time she went missing, relatives said. 
 
 Her body was not discovered until nearly 24 hours later after the family repeatedly contacted the hotel and police, at one point knocking on doors until officers stopped them. Jenkins was pronounced dead on the scene at 12:48 a.m. Sunday, according to the medical examiner's office. 
 
 Jenkins' mother said Sunday she was told by police that her daughter apparently let herself into the freezer while drunk and died inside. An autopsy Sunday afternoon failed to determine a cause of death, and the medical examiner's office said it was awaiting toxicology tests and further investigation by police. 
 
 Rosemont spokesman Gary Mack said police are reviewing a Facebook Live video that appears to show Jenkins sitting on a bed in a hotel room with other people around her. 
 
 The video — which has gotten more than 3 million views — features a woman in mirrored sunglasses talking to the camera. Reflected in her glasses is the other side of the hotel room, where Jenkins appears to be sitting. 
 
 Kenneka Jenkins, 19, was pronouced dead early Sept. 10, 2017, after she was found in a walk-in freezer at the Crowne Plaza hotel in Rosemont.

 Mack said authorities have identified most of the people on the video. 
 
 "Yes, they've looked at it and continue to look at it and all the other social media videos and posts," Mack told the Tribune on Monday. "They are leaving no stone unturned as far as trying to corral everyone they can and talk to them and interview them about what happened and what was going on that night." 
 
 The Facebook video has stoked outrage on social media, where many users believe Jenkins met with some kind of foul play. Some have threatened to harm people in the room. 
 
 The video has been shared online more than 46,000 times and has spawned a trending hashtag on Twitter bearing Jenkins' name. 
 
 But Mack said that to seasoned investigators, this type of social media attention has become commonplace and it doesn't hurt the investigation. 
 
 "In law enforcement this kind of social media has become king, so everybody with a camera is a reporter now, and they're just taking it in stride as best they can," Mack said. 
 
 Mack said it may take weeks to determine what happened. A toxicology test routinely takes weeks or months to complete, and the time it takes to finish a police investigation can vary greatly. 
 
 "I don't think anything has been ruled in or ruled out at this point," Mack said. "It's just considered a death investigation at this point." 
 
 Records from the Occupational Safety and Health Administration show that walk-in freezer deaths are rare, but one happened last year at a hotel in Atlanta. Carolyn Mangham, who worked at the Westin Peachtree Plaza, was trapped in a freezer for 13 hours at temperatures below minus 10 degrees. 
 
 An exit button inside the freezer was supposed to allow people to open the door if it shut behind them, but authorities found it sometimes malfunctioned, The Associated Press reported. 
 
 Mack said he didn't know if the freezer was on at the time. "If it was unused, I don't know. Sometimes people keep refrigerators on all the time even if they're unused," he said. 
 
 It also remains unclear how Jenkins was found and who discovered her body. 
 
 Her family members have said they went to the hotel at 5 a.m. Saturday looking for her and repeatedly asked the hotel and police to search for her. A search was begun around 1:30 p.m. after the family said it was allowed to file a missing persons report. 
 
 Steven Shapiro, director of the hospitality and tourism law program at American University's Washington College of Law, said hotel managers are reluctant to intrude upon their guests' privacy, even when someone from the outside indicates there might be an emergency. 
 
 "Generally speaking, they're going to bring in the police … and let them do the investigation," he said. "Because people try to dupe them, they're generally not going to open (a guest's) door and say, 'What are you doing?' Their first obligation is to their guest, and not to the person who comes in off the street." 
 
 Jenkins' mother said she doesn't believe the hotel began reviewing surveillance video until 3 or 4 p.m. Jenkins' body was found around midnight. 
 
 Mack said he didn't know if the surveillance video led searchers to the freezer. "I suppose they searched everywhere," he said. "The surveillance video will reveal a lot, I suppose. 
 
 "As far as who found the girl's body, they're not saying on that," Mack said. "That's something that's part of the investigation and they're not releasing." 
 
 He said police also were not disclosing whether there were any signs of trauma to Jenkins' body.

– Authorities on Friday officially closed their investigation into the death of Kenneka Jenkins, who was found "frozen solid" in a freezer in the unused kitchen of a Chicago-area hotel Sept. 10, the Chicago Sun-Times reports. According to the Chicago Tribune, Rosemont police—after a thorough investigation that included interviews with 44 people, dozens of hours of surveillance footage, forensic analysis on multiple cellphones, and more—have determined the 19-year-old's death to be accidental, stating there is "no evidence that indicates any other conclusion." Police say none of the conspiracy theories about foul play floated on social media "were supported by facts," CNN reports. Police say there is no evidence Jenkins was forced to drink or take drugs at the party where she was last seen. Jenkins' family doesn't appear satisfied with the conclusion of authorities. Along with the closing of the investigation, police released documents related to the case on Friday. Lawyers for Jenkins' mother say the "graphic and disturbing" photos of Jenkins' body in the freezer "inexplicably show portions of Kenneka's body exposed" and "raise more questions ... than they answer." Photos of Jenkins' body in the freezer show her with her jean jacket still on but her shirt pulled up "exposing her breasts." This could be the result of what scientists call "paradoxical undressing" in which a hypothermia victim removes clothing despite freezing to death. A medical examiner had already concluded Jenkins died from hypothermia with no signs of internal or external trauma. In a statement, police called her death "especially sad."
