Knife at OJ Simpson’s home ‘was found by a citizen’

US detectives are investigating a knife purportedly found some time ago at the former home of OJ Simpson.

The former American footballer was controversially acquitted of murder charges over the 1994 stabbings of his ex-wife Nicole Brown Simpson and her friend Ron Goldman.

The knife was supposedly found by a citizen, possibly during demolition of the home years ago, and turned over to a now-retired police motorcycle officer who was working as a filming location security guard, Los Angeles police captain Andy Neiman said.
