As per NBC, it was on August 17, 2014, when Rob was shot to death in his workplace at the BNSF railyard in Tehachapi. Authorities initially considered the situation to be a case of gang robbery.
From the surveillance footage around the workplace, the detectives tracked a man limping around the workplace. Outside of the railways, detectives observed a group of people on motorcycles. Police could identify most of their suspects, except for one masked man on the motorcycle.
Investigators didn't find any more concrete evidence that could direct them to a culprit. The case remained on a hiatus for two weeks until one of Rob Limon's friends, Jason Bernatene, reached out to the officials.
