 The UPF report states that Rice was found slumped in a chair on the balcony of his room at the Lake Victoria Serena hotel in Kampala, his head resting on a table and blood coming out of his mouth and nose. Jeff Rice was declared dead on arrival," Uganda Media Centre spokesman Fred Opolot tells E! "Ms. Fuller is slowly recovering, and when she is recovered enough we will be able to talk to her and find out more about what happened," Uganda Police Force spokesman Asuman Mugenyi said. "It has been truly amazing to receive messages from people around the world who speak so highly of Jeff. Although she is responding to the treatment, she is not yet available to explain what transpired." Because cocaine was also found in Fuller's system, she may have broken Ugandan drug laws and will need permission from Interpol to be allowed to return home to South Africa, UPF spokesman Asuman Mugenyi told ABC. According to Ugandan police, the two are believed to have voluntarily ingested the substance. Not even a single bruise on Rice's body," Mugenyi said. Details are sketchy, but the source said that after refusing to give in to the demands of local thugs, Rice and another facilitator ended up very sick with poisoning of some kind. "I was shocked," Josh Gates, a friend of Rice's told ABC News. Jeff was on a film production in Uganda and was doing what he loves...He was a true asset to the film industry worldwide and Africa was his 'home'. Rice was a veteran producer who worked on the latest season of the hit reality series "The Amazing Race" and the Emmy-nominated Animal Planet series "Whale Wars." In addition to raising two young kids, Rice and his wife, Sally Blackman, operated a television and film production company called SB Productions in Durban, South Africa. Stuart Fuller said he is now with his daughter at the hospital in Kampala.
– Police in Uganda have dismissed reports that thugs poisoned Amazing Race producer Jeff Rice, saying the American appears to have died from a cocaine overdose. Rice was found slumped in a chair on his hotel balcony, and an autopsy found the drug in his system, officials say. Rice's assistant Kathryn Fuller, who remains critically ill in a local hospital, also tested positive for the drug, and may not be allowed to leave the country for treatment in her native South Africa until after questioning. Police believe the pair voluntarily ingested the drug, contradicting reports from Rice's wife that he was apparently poisoned after rebuffing a shakedown by local crooks, ABC reports. The two were in Uganda filming a documentary about a non-profit organization that provides the poor with hearing aids. "It is unfortunate," a government official tells E! Online. "He came to this country to do a good program—he came across as someone of humanity. It is unfortunate he has passed away, and really, our condolences to his family."
