Further investigation of the sign language interpreter that stood next to world leaders, including President Obama, during the four-hour ceremonies for Nelson Mandela in South Africa shows that he has a rather checkered past.

The supposed sign language interpreter, Thamsanqa Jantjie, stunned audiences viewing the ceremony worldwide and enraged the interrnational hearing impaired community when he jestured nonsense as world leaders spoke in South Africa this week. Hearing impaired worldwide quickly saw through the poorly disguised ineptitude of the interpreter as he signed non-words over the air.

Further investigation of the man, who has previously been accused of murder, rape, theft, breaking and entering, and kidnapping, caused many to wonder how a man with such a past was allowed so close to world leaders and called into question the security surrounding the event.

Jantjie, who has been diagnosed with schizophrenia and spent 19 months institutionalized for the condition, has criminal charges going back to 1994. It was then that he was charged with rape, but was acquited of those charges, because he was deemed unfit to stand trial, but was convicted of theft the following year. Although he was sentenced to three years on that charge, it is unknown if he did the jail time for the offense, as he was charged with breaking into a house just two years later. Other charges ensued and culminated with Murder, Attempted Murder, as well as a kidnapping charges in 2003. The case went to high court in 2004, and was finalized in 2006. But, nothing can be found on the case as all records in the court file are missing.

According to the Associated Press, Jantjie told them in an interview that he was hallucinating while on the stage and heard voices and had seen angels. He apologized for the incident but stated that he did a proper interpretation. He also told AP that he had violent episodes but was on medication.

State security for South Africa stated that they had looked ito the criminal past of those participating in the service and said that they do have a criminal investigation into the case.

The South African government said that they had tried to look into the company that hired the fake interpreter, but that the company’s owners had “vanished into thin air.”
