Summary: Buffalo, NY (WKBW)- Joan Hoffman will never forget April 12th 1975; it's the day her husband Robert left for work and never returned home. Robert Hoffman was a driver for a local taxi cab company and left his Buffalo home around 6:30pm for work. Joan says her husband picked up his 2nd fair on Niagara Street near Carolina Street in the Queen City at the beginning of his shift. Hours later, Robert was later discovered miles away on Hotaling Drive in Buffalo shot to death. A patron of Sully's Tavern found him inside his parked cab.

"I told him not to go because I didn't feel right about him leaving for work that night, but he told me everything was going to be ok," said Joan Hoffman.

36 years later there have been no arrests in the case. Hoffman's family is keeping hope alive and are encouraged by the advances in technology and DNA profiling. They hope the advances will help to solve this cold case.

"It's been 36 years and it's not just a cold case, it's in the freezer. It's been way too long," said Joan Hoffman. "This guy had to have left DNA. There's got to be DNA, if they would just look at it again."

A Buffalo Police Spokesperson says the case remains active. Anyone with information on this case is asked to call the Buffalo Police Condifential Tip Call Line at 716-847-2255. Joan Hoffman says she will never give up hope and believes justice will be served someday.
