BOISE — On December 17, 2014 two men stormed into a Jackson's food store in Notus and murdered the clerk in cold blood.
Christopher Reese was 25-years-old at the time and four years later investigators are asking the public for help once again as they continue to search for clues in this murder.
"It is a case that continues to haunt us, it is a case that continues to haunt the Reese family," said Canyon Couny Sheriff Kieran Donahue. "We are not stopping, we are not giving up, we are going to chase this down to the very end."
Investigators recovered forensic evidence after the two men left the store with a safe in Reese's car, that evidence has lead to several dead ends but at the same time has helped authorities narrow their search.
"Please if you have any information on who did this crime come forward," said Ted Arnold of Crime Stoppers. "You can contact the sheriff's office or remain anonymous through Crime Stoppers."
The owners of Jackson's food stores have doubled the reward to $100,000 for information that leads to the arrest of the two men and Lamar Advertising will donate at least four billboards that people will see off the interstate in between Nampa and Boise.
Sheriff Donahue also has a warning for people who may know these two suspects.
"These men have likely talked to somebody and those people should be coming forward, if you withhold that type of information we will prosecute you," said Sheriff Donahue.
If you have information you are urged to contact the sheriff's office or you can do so anonymously through Crime Stoppers by calling 208-343-COPS, on the internet at 343cops.com or through an app called p3tips.
