As the investigation into Stanislaus County Sheriff’s Deputy Dennis Wallace’s death continues, Stanislaus County Sheriff’s Detectives are asking for the public’s help. Detectives are working on establishing a timeline of everywhere the suspect, David Machado, may have been before and after the Nov. 13 shooting at the Fox Grove Fishing Access near Hughson.

The longtime deputy, who served in Hughson, was gunned down on Sunday morning; Machado was arrested later on in the day in Tulare County.

Detectives also want to speak to anyone who has had prior contacts or any incidents with David Machado. Anyone who believes they may have seen David Machado at any time Sunday, Nov. 13, or had dealings with him in the past, is asked to contact Sheriff’s Detective Josh Sandoval at 209-525-7073.
