Sun Gym gang
The Sun Gym gang was active in the Miami, Florida area, during the mid-1990s and were responsible for the murders of Frank Griga and Krisztina Furton along with the kidnapping, extortion, and attempted murder of Marc Schiller. The gang was composed mostly of bodybuilders who frequented the Sun Gym in North Miami, Florida, including Daniel Lugo and Noel "Adrian" Doorbal.
Pete Collins published a three-part series in the Miami New Times in 1999 and 2000 chronicling the stories of the gang titled "Pain and Gain" which was then loosely adapted into the 2013 film Pain & Gain directed by Michael Bay.
