BLOUNTVILLE — A Sullivan County constable has been indicted on multiple charges after allegedly lying about serving court documents. Larry H. Mullenix, 62, of Mullenix Lane in Kingsport, turned himself in at the Sullivan County Sheriff's Office on Friday. He later posted $7,500 bond and was released. The case against Mullenix was investigated by the SCSO and presented last week to a Sullivan County grand jury.
