A Provo, UT, police officer, who died more than a decade ago, is just now being recognized as having died in the line of duty.

Officer Trenton Halladay served in law enforcement for a decade at the Provo Police Department. For most of his career, Halladay worked on a task force responsible for busting countless meth labs that plagued Utah County in the late 1990s and early 2000s, Desert News reports.

As Trenton's wife Lisa watched her husband and the father of their two boys do what he believed in to keep the community safe, she also watched his health decline. Trenton Halladay was diagnosed with cancer in 2006, and a doctor gave him six months to two years to live. Less than six months later, he passed away at the age of 37.

Lisa Halladay believed his death deserved line-of-duty recognition, calling it a “slow-moving bullet.”

Organizations including the Utah State Fraternal Order of Police and Concerns of Police Survivors agreed and began what would become a 16-year battle to call Trent Halladay’s death a duty death.

This year Officer Halladay's name was carved into the National Law Enforcement Officers Memorial in Washington, DC, and his name was read during the Candlelight Vigil.
