Story highlights After 27 years in prison, lawyers claim new evidence could free ex-millionaire 
 
 Kris Maharaj's lawyers say he was framed for a drug-money hit ordered by Pablo Escobar 
 
 Prosecutors say Maharaj shot and killed a father and son in a Miami hotel 
 
 It sounds like an episode from a 1980s TV police drama: A wealthy businessman claims he was framed for two Miami murders allegedly ordered by Colombian drug lord Pablo Escobar. 
 
 Nearly 30 years ago, international food importer and newspaper owner Krishna "Kris" Maharaj, a British citizen, was living the good life in South Florida. He had owned luxury cars and horses that raced against thoroughbreds held by Queen Elizabeth II. 
 
 Then, in October 1986, police arrested Maharaj in the shooting deaths of his business partners Derrick Moo Young and his 23-year-old son Duane. 
 
 Despite having an alibi, Maharaj was charged with murdering the Moo Youngs because they allegedly had cheated him out of more than $400,000. He was found guilty and sentenced to death -- a penalty that was later reduced to life in prison. 
 
 And there Maharaj has remained for 27 years.

 Then, in April this year, a Florida judge granted Maharaj a chance that could open the door to freedom. 
 
 Florida 11th Judicial Circuit Judge William Thomas held a hearing in November to determine if new evidence from Maharaj's lawyers "undermines confidence in the verdict," according to court documents. Defense attorneys also must establish that the new "evidence would probably produce an acquittal or less severe sentence on retrial." 
 
 Maharaj's lawyers said evidence suggests that the murders were committed by former members of Escobar's infamous drug cartel. 
 
 In the late 1970s and early '80s, Escobar cashed in on the exploding popularity of cocaine in the United States, according to reporter Mark Bowden, author of "Killing Pablo." Leading the Medellin Cartel, Escobar was responsible at one point for almost 80% of Colombia's cocaine exports, making him the seventh richest man in the world, Bowden told CNN 
 
 Escobar was killed in a rooftop shootout with authorities in 1993. 
 
 According to a motion filed in January by Maharaj's attorneys, a "Colombian drug cartel member confirmed that the Moo Young murders were committed at the behest of Pablo Escobar." 
 
 "The Moo Youngs were laundering money for the Colombian cartels," the defense motion said. "This is what precipitated their murders." An ex-cartel member confirmed that "Maharaj was not involved in the murders of the Moo Youngs, and that they had to be eliminated because they had lost Colombian drug money," according to the defense motion. 
 
 Maharaj was sentenced to death in 1987. Before he could be executed, that sentence was reduced to life in prison. 
 
 "We've got several Colombian cartel people to say, 'We did the murders,'" Maharaj defense attorney Clive Stafford Smith told CNN on the phone in June. 
 
 The defense team also alleges Florida prosecutors covered up evidence in the 1987 trial that could have proved Maharaj's innocence. 
 
 Although prosecutors said they stand by the decades-old case, in a June e-mail to CNN, a state attorney spokesman wrote, "Now that we are re-engaged in litigation on this matter, it would be inappropriate for us to be commenting at this time." 
 
 Prior to the hearing, strongly worded arguments flew back and forth via filed court documents. In January Assistant State Attorneys Penny Brill and Sally Weintraub wrote that a defense motion for the new hearing was based on "hearsay and inadmissible evidence." 
 
 "None of [the potential witnesses named in the defense motion] have any first hand knowledge, provide no admissible testimony or evidence and only attempt to further the nonsensical and wholly speculative theories of the defense," the prosecution document said. 
 
 Colombian drug lord Pablo Escobar was killed by Colombian special forces after being discovered hiding in a house in Medellin in 1993. 
 
 "The only thing that is obvious to anyone who really looks at these fantastical allegations by the defendant is that they are empty and have no substance," wrote the prosecutors. 
 
 Now aged 75, Maharaj has been in poor health, Smith said, although he seems to have improved. 
 
 "When we got this hearing, and when we started learning about these Colombian witnesses who were corroborating his innocence, Kris really cheered up," said Smith. "I think he's now trying to walk more and not use his wheel chair and so forth." 
 
 Defense attorney Ben Kuehne said the "circumstances of this crime were not as presented to the jury by the prosecution," reported Miami TV station WTVJ Prosecutor Brill reportedly countered , "I haven't heard one thing from the defense that indicates that this is admissible evidence." 
 
 In the wake of the hearing, Judge Thomas is expected to set a court date when he could issue a ruling. 
 
 But the odds are stacked against Maharaj. The burden of proof is high. Florida's Supreme Court has already upheld his conviction. 
 
 Derrick Moo Young's daughter was asked in 2007 about continued efforts to exonerate Maharaj. "It's all been hashed out before," she told the Miami Herald . "It's a waste of tax dollars." 
 
 Prosecutors' evidence against Maharaj is significant. 
 
 Police found Maharaj's fingerprints in the guest room at Miami's Dupont Plaza hotel where the shootings occurred. Maharaj says he was there for a meeting, but he departed before the Moo Youngs were killed. Nineteen fingerprints found at the crime scene have never been identified, according to the defense motion. 
 
 Maharaj told CNN's "Death Row Stories" that he left the hotel and drove 25 miles to Fort Lauderdale to have lunch with one of his newspaper employees. The employee signed an affidavit as an alibi witness. The restaurant manager, Ron Kisch, told "Death Row Stories," he remembered seeing Maharaj having lunch that day. 
 
 "It doesn't seem like there's any way possible that he could have killed people at 12 o'clock and then been in for lunch sometime between 12 and 2," Kisch said. Five other witnesses came forward saying Maharaj was with them on the day of the murders, "Death Row Stories" reported. 
 
 Across the hall from the murder scene at the time of the killings, said the defense team, was a Colombian hotel guest named Vallejo Mejia. 
 
 Maharaj was convicted of killing Duane Moo Young, 23, and his father in a Miami hotel room. 
 
 Police briefly questioned Mejia at the time, according to defense documents. He was a "longtime money launderer who was frequently in Miami," the documents said. More recently, defense lawyers said in the documents, they had been "able to establish that [Mejia] was a senior cartel operative." 
 
 During his entire imprisonment, Maharaj's wife Marita has been working to keep her husband's confidence high, said Smith. It's important to her that Maharaj believes he will eventually be exonerated. "She is his rock," Smith said. "They talk every day on the phone ... and she goes to see him every Sunday." 
 
 Earlier this year, Marita wrote in the New Statesman , "I pretend to myself that Kris is traveling. When I have five minutes on the phone with him in the evening, I pretend to myself that he is talking to me from a trip, not from a cell." 
 
 Smith sees Maharaj quite often lately at a medium security correctional facility outside Miami. Authorities allow them to sit together at a table in a largely empty room with a guard watching nearby. 
 
 "I don't think there's a case that's quite as absolute as Kris'," said Smith. "I mean we've got an alibi — we've got everything. It's just really shocking." 
 
 Smith admits he's become "obsessed" with freeing his client -- partially because of guilt. "I've represented the guy for 20 years and I failed him. And it really makes you think, 'How on Earth could you lose a case like this?'" 
 
 Virtually penniless, Maharaj faces financial challenges as well as health issues. "If he gets out, he'll probably go back to Britain and set up another business," said Smith. "Kris is fairly unstoppable." ||||| Lawyers representing Krishna Maharaj, a British businessman who has spent the past 27 years in a Florida prison for a double murder that they say he did not commit, released on Friday details of the 53 witnesses and 498 documents they plan to call on in the hope of persuading a judge to order a retrial. 
 
 
 
 Next Wednesday, the 11th judicial circuit court of Florida in Miami will set a date for a full evidentiary hearing into the Maharaj case. The hearing will constitute his greatest chance in almost three decades to prove his innocence for the murders of his business partner Derrick Moo Young and Young’s son Duane in the Dupont Plaza hotel in Miami on 16 October 1986. 
 
 Maharaj, 75, was sentenced to death in 1987, and though he was taken off death row in 2002 he was resentenced to life imprisonment. He is currently held in a prison in south Florida. 
 
 The newly released documents underline the massive case for exoneration that has been built up by Maharaj’s lawyers. One of them, Clive Stafford Smith of the legal support group Reprieve, who has written a book on the case, The Injustice System: A Murder in Miami and a Trial Gone Wrong, told the Guardian: “Kris Maharaj is so patently innocent that it is unimaginable to me that the state of Florida does not let him go. It is a very sad day when the government desperately wants to keep the wrong person in prison, such that they will not even investigate who the real killers are.” 
 
 In his bid for a retrial, the Trinidad-born Maharaj asserts that he was framed as the murderer to help cover up the involvement of Colombian drug cartels in the killings. The prisoner will present the court with evidence that the victims had been laundering huge sums for the Medellin drug cartel. 
 
 Among the witnesses to be called at the evidentiary hearing will be six people who can testify that Maharaj was 30 miles away from the Dupont Plaza hotel when the murders happened. Further testimony will be provided alleging that another named individual carried out the killings, and illuminating the motive for him doing so. 
 
 Other witnesses will be called to support allegations of perjury by key state witnesses at Maharaj’s trial. 
 
 The newly disclosed list of witnesses the lawyers intend to call at the full evidentiary hearing also includes several investigators and attorneys involved in the case, fingerprint experts and former Miami police officers. Among the pile of documents to be presented are some allegedly demonstrating drug dealing and money laundering by the Youngs and records from the hotel. 
 
 The case is being considered by Judge William Thomas. Ordering a full evidentiary hearing on 24 April, he stated that Maharaj would be granted a new trial if he could persuade the court that the new evidence that will be presented at the full hearing was of “such nature that it would probably produce an acquittal on retrial”. 
 
 Lawyers for the state have claimed much of the new material is hearsay and inadmissible in any new trial. The judge said he would take a view on admissibility at the evidentiary hearing.
– After 27 years in prison, Krishna "Kris" Maharaj may finally get a chance to prove what he's been claiming for years: that he was framed for a pair of murders actually ordered by infamous Colombian drug lord Pablo Escobar. CNN has a profile on Maharaj's case detailing how, in 1986, he was arrested for the Miami murders of his business partners Derrick and Duane Moo Young—even though he had an alibi. Police said the Moo Youngs had cheated the former millionaire out of $400,000. He was found guilty and sentenced to death. That sentence has since been reduced to life in prison, but in April a Florida judge scheduled a November hearing to determine if new evidence could undermine the verdict. Maharaj's lawyers have 53 witnesses and 498 documents on tap, according to the Guardian. "We've got several Colombian cartel people to say, 'We did the murders,'" one lawyer says. These cartel witnesses say that the Moo Youngs were money launderers for the cartel, and were killed because they lost some of the money. The lawyers also say they can prove that prosecutors hid evidence that would have proved Maharaj's innocence. But in court filings, prosecutors say the evidence is all "hearsay and inadmissible."
