The Dos Palos District Cemetery hosted a burial service for O'Banion yesterday.
The 74-year-old passed away last Sunday after he battled heart and lung issues, in addition to a bout with COVID-19.
O'Banion spent 28 years serving on the Merced County Board of Supervisors.
When he retired in 2018, he was the second-longest tenured supervisor in the state.
Prior to his time on the board, O'Banion was a councilman and Mayor of Dos Palos.
