DENVER - A billboard on Colfax Avenue asks people to help find the person who hit and killed two young boys crossing the street with their mother.
Zamay Khan, 8, and his brother, Azat Khan, 6, were killed at 14th Avenue as they were crossing Yosemite Street on March 22.
Their mother, Zama Bee, was also hit. She suffered a broken leg and arm, but survived.
The new billboard is in a high-traffic area about 4 miles from where the hit-and-run happened. The billboard shows Zama Bee with her two boys and says, "Someone knows who killed our sons."
Zama Bee speaks little English, but with the help of a translator she said she is thankful to the community for the support in finding the person responsible.
"I think that, why do I deserve to be like this? Why is he killing my two sons when we didn't do anything to him," Zama Bee said.
As she showed pictures of the six-year-old and eight-year-old, the mother broke down sobbing into her jacket. She said both boys loved to ridge bikes and said her oldest was very smart.
"He learned English very quickly. He often helped translate," Zama Bee said. "When someone called, he would just pick up the phone and talk to them."
On the billboard is a grainy surveillance picture of the SUV that hit the boys. Investigators believe it was a white or silver, older model, Cadillac Escalade, likely 2002-2007, ESV model. Investigators said it likely had damage to the front end from the collision.
Metro Denver Crime Stoppers said it has received what it called a sizable donation to offer up to $20,000 for information which leads to an arrest and conviction in this case. Anyone with information in this case is asked to contact Metro Denver Crime Stoppers at 720-913-STOP.
Metro Denver Crime Stoppers said it has paid out over $600,000 in awards to citizens who have helped solve thousands of cases.
