|First appearance||High Anxiety|
|Voiced by||Mac Davis|
Sheriff Mumford appears in High Anxiety. He has bragged to to media that he's never let a murder go unsolved in Hemlich County, although he was only talking about two total cases. He works out of Heimlich County Sheriff's Station and when Debbie Grund was killed, he was the lead investigator. Some of his actions during the case were highly questionable, such as his witch-hunt tactics in the investigation, embrace of the media for seemingly his own personal gain, and attempting to get free food from Sugarfoot's while on duty. Texas Ranger Lester Payton was the one that solved the case much to Sheriff Mumford's dismay.
