(WASHINGTON) -- Lingering questions about the murder of journalist Daniel Pearl may finally be answered, thanks to an extensive investigation by students at Georgetown University.
Pearl was on assignment for The Wall Street Journal in Karachi, Pakistan, when he was kidnapped on Jan. 23, 2002 and beheaded days later at the hands of al Qaeda operatives.
The Georgetown students found that 27 different men were allegedly involved in the crime and that 9/11 mastermind Khalid Sheikh Mohammed was almost certainly the masked executor who took Pearl's life.
The findings of the three-year investigation were published today in an expansive report, titled "The Truth Left Behind: Inside the Kidnapping and Murder of Daniel Pearl." The team of 32 students who worked on the project were led by former Wall Street Journal reporter Asra Nomani and Georgetown University professor Barbara Feinman Todd.
According to the report, only four of the 27 men allegedly involved in the murder have been charged and convicted, and 14 others remain free.
Others are in custody but yet to be charged in the crime, including the man who was once al Qaeda's second-in-command, Khalid Sheikh Mohammed, who is currently being held at Guantanamo Bay.
"The Pearl Project reveals that justice was not served for Danny," said Nomani in a release.
The students unearthed information revealing that U.S. officials have used a "vein matching" technique to verify that Khalid Sheikh Mohammed was in fact the man who beheaded Pearl.
The al Qaeda leader had already confessed to the murder, but officials were concerned as to whether the confession was a result of waterboarding and might not be admissible in court.
