A murder case gone cold.
Now, nearly two years later -- a family is trying to to what it can to put the people who killed their 20-year-old son behind bars. An incentive for the public to help out: a $20,000 reward.
Life has changed for the Corbut family ever since their son -- Zachary Corbut -- was killed on October 13, 2015.
"Holidays aren't the same, birthdays aren't the same, family events aren't the same," his mother, Ann Corbut said.
The night he was killed started with a home invasion in Midtown.
"There was a demand for some money and drugs," his mother said. "The two roommates were pistol whipped. He came out of the bedroom and he was shot multiple times."
Mrs. Corbut explained she speaks with the Tucson Police Department regularly every month, hoping for some kind of new development. But she says unfortunately, there hasn't been any lately.
"There have been some leads," she said. "But they don't have anything to go on, you know, right now."
With the case gone cold, the Corbut family is now doing whatever it can to get the public to help out in finding the people responsible for their son's murder. They live in Houston, Texas, but have taken out signs all across Tucson with their plea. Multiple bus benches, bus stops, and billboards have his picture on it, the $20,000 reward advertisement, and the words, "Who Killed Me?"
"The billboards, the bus benches, the bus displays," Mrs. Corbut said. "Those will be going on for a while just to try to bring attention. There's somebody out there that knows more about this."
Now, the family is pleading with the public to help out, not just for their sake, but for the sake of the Tucson community.
"Not only were they a threat to our son, but they remain at large and are a threat to the Tucson community," Corbut said. "I don't want another family to have to go through what our family has endured."
If you have any information that will lead to the arrest of the people responsible for Zach Corbut's murder on October 13, 2015, you are eligible for the $20,000 reward if you call 88-CRIME.
