Deputies and family members, including Owen's wife Tania, will be standing vigil at the spot where the 53-year-old was killed throughout the day Monday as a special tribute for 24 hours.
Sgt. Own was shot five times outside an apartment complex on Oct. 5, 2016, after responding to a burglary call in Lancaster.
He was answering a report of a break-in when he confronted the suspect, Trenton Lovell, at gunpoint. Lovell shot the veteran sergeant once in the head before standing over him and firing additional fatal shots.

A second deputy who arrived on the scene shot and wounded Lovell, who attempted to steal the officer's car before fleeing on foot. Lovell then broke into a nearby home and held two teenagers hostage for an hour. The teens were not physically injured, and Lovell was captured after leaving the home.
Lovell had two prior convictions and was on parole at the time of the slaying of Sgt. Owen.
The 31-year-old pleaded guilty in the case and was sentenced to life in prison without the possibility of parole earlier this year.
