PHOENIX - There's a new development in the investigation of a brutal crime in Phoenix that has gone unsolved.
49-year-old Dinya Farmer was gunned down while driving north on State Route 51 near Thomas Road on September 7th.
On November 22nd, police announced $21,000 reward in this case.
When Farmer called 9-1-1, she stated "three Mexican guys in a light-colored truck" started following her at Broadway and 7th Avenue. They followed her all the way to SR51 northbound between McDowell and Thomas. She told the operator she was nervous, then they were right next to her.
An unknown noise was heard and police later determined it was gunfire.
A bullet hit Farmer in the head, killing her.
"Everyone knows Thanksgiving is just around the corner. Our hope is someone will come forward as a result of the upcoming holiday and we need them to do the right thing," said Sgt. Jamie Rothschild.
It's been 2.5 months with no break in the case. Police were tight-lipped Tuesday morning, but hopeful.
"We are not worried at this point. We have cases that go on for many years that are solved and somebody in the public held onto info for years," said Sgt. Eric Lumley.
