A knife was reportedly found on the grounds of OJ Simpson’s former home, and kept since the late 1990s by a retired police officer. According to multiple reports a construction worker found a folding buck knife years ago, possibly in 1998, buried on the grounds of the former NFL player’s L.A. mansion. The worker took the weapon out onto the street and approached a police officer, who demanded he hand it over. Despite taking the weapon off the construction worker the officer kept it for years without telling anyone.
