Updated on March 17, 2021 at 9:37 pm Los Angeles County District Attorney George Gascon said Tuesday his office would review past prosecutions that involved a retired LAPD homicide detective, who was apparently recorded on cell phone video in Valencia using a racial slur during an argument that followed a minor traffic collision. “The video in question is disturbing and involves a former homicide detective exhibiting racist tendencies,” Gascon said via Twitter. He said the DA’s office, “is taking immediate action and has identified several cases where this individual was a witness.” Download our NBC DFW mobile app for Apple or Android to get alerts for local breaking news and weather.
