A chiropractor from Parkland pleaded guilty Monday to five criminal charges related to a staged accident insurance fraud conspiracy in South Florida, court records show. Lawrence Schechtman, 45, pleaded guilty to one count of mail fraud conspiracy and four counts of mail fraud that occurred between 2009 and 2012. Prosecutors said Schechtman, who worked at clinics in Palm Springs and Miami, signed off on treatments for people who fraudulently claimed they were accident victims as part of a staged-accident fraud ring.
