Nine years ago, the state of Florida received documentation from a security firm vouching for the mental health of Omar Mateen, who launched a bloody attack this week on Orlando nightclub patrons. But the psychologist whose name appears on the document in state records said Friday that she never evaluated [Mateen]. In fact, she wasn't even living in Florida when the evaluation was supposedly completed. The revelation Friday became another source of scrutiny for the G4S security firm, which was known as Wackenhut at the time. The psychological evaluation done for the company, which is required under state law, cleared Mateen to carry a firearm as a private security guard. What I do know is that in September 2007, I was not living or working in Florida, I was not performing any work for Wackenhut, and I did not administer any type of examination to Omar Mateen," Dr. Carol Nudelman, who now lives in Colorado, said in a statement. The global security firm - which does work in more than 100 countries - is locally based in Jupiter. Its operations have come under scrutiny a number of times over the years. In the mid-2000s, G4S was accused of overbilling Miami-Dade County taxpayers of at least $3 million for security services that were not actually provided. But a criminal case against company employees fizzled in 2012.
