DENVER -- They served their country, now police are hoping someone will provide information that will aid in finding those responsible for taking their lives.
Rewards are increasing in the homicide cases of 24-year-old Travis Mason and 63-year-old Richard "Gene" Hammond.
Hammond, a retired Marine major, father and grandfather, was also the El Paso County school district transportation director.
The Denver Police Department said on Valentine’s Day, Hammond left his home near Bruce Randolph Avenue and York Street to head to work in Fountain between 3:30 a.m. and 4 a.m.
He was driving a 2012 Subaru Impreza sedan. Hammond’s body and the car were discovered less than a half-mile from his house.
Police said he died from a gunshot wound. Hammond was buried with full military honors at Fort Logan National Cemetery.
He is described by his co-workers as someone of excessive ethical character.
A $13,000 reward is being offered for information leading to an arrest.
Mason was a Marine and young father. Police said he was killed on June 18 while working security at Green Heart Dispensary at 19005 E. Quincy Ave. in Aurora.
Investigators are looking to question two men who were pictured in a surveillance video. Both wore dark-colored hooded sweatshirts with a white logo.
One wore a red-and-white horizontal striped shirt underneath, jeans and gray shoes with white stripes and blue shoelaces. The other wore jeans and maroon converse-style gym shoes.
Mason dreamed of becoming a police officer and was working security on a temporary basis. A $50,000 reward is being offered for information leading to an arrest.
Anyone with information in either case is asked to call Metro Denver Crime Stoppers at 720-913-7867.
