A 23-year-old Barnesville man charged with the March murder of local cab company owner John Dixson is apparently unhappy with living conditions at the Lamar County jail.Jamarris Latuan Williams, a local thug with a long criminal history, allegedly stabbed Dixson, 76, in the throat, stole his cab and left him to die in an isolated ravine in southeast Lamar County.Williams has also been a menace at the jail since being locked up.Confined to an isolation cell for his own safety, Williams has repeatedly flooded his new digs by flushing items down his toilet. He routinely kicks at his door, making a nuisance of himself.’He has kicked out his lights two or three times. He can use the broken bulbs as a weapon so now he lives in the dark. I don’t know what his problem is,’ LCSO spokesman Brad White says.Whatever his complaint, Williams won’t be going anywhere soon. His case was not presented to the June term grand jury because crime lab analysis on evidence is not yet complete.The next grand jury convenes in September.Barring a guilty plea, any trial in the case would take months or years to prepare after an indictment.
