Inmate Conspiracy

For immediate release:

Deputies at the Gwinnett County Sheriff’s Office uncovered a conspiracy between three inmates to prevent their respective victims from testifying against them at trial.


An alert deputy became suspicious when two seemingly healthy inmates arrived at the jail’s medical unit appearing to be feigning medical emergencies. The deputy investigated further and discovered that the two inmates, Alfredo Sosa (18 yrs old) and Miguel Luis Camacho-Gonzales (22 yrs old), were co-defendants in an armed robbery. A cell search of Sosa’s cell yielded a handwritten note entitled, “Plan To Free Us”, written by a third inmate, Jerome Derrell Welch (22 yrs old).



The information was provided to deputies assigned to the Investigative Services Division, who quickly identified that all three inmates shared a common victim, Matthew Barrett. According to the plan drafted by Welch, Camacho-Gonzales would make arrangements for his mother, Maribel Gonzalez (42 yrs old), to send money to Camacho-Gonzales’ girlfriend, Jillian Michelle Dumke (23 yrs old). The money was to be utilized to pay victim Matthew Barrett to “disappear” before Welch’s upcoming March trial. Western Union records reflect that Maribel Gonzalez paid a sum of $1,000.00 to Matthew Barrett.



Recorded phone conversations revealed that in exchange for this payoff, upon his release from jail, Welch would ensure that Sosa and Camacho-Gonzales’ other victims in an unrelated armed robbery case would not appear to testify at their trial. Western Union records reflect that Maribel Gonzalez paid a sum of $1,000.00 to Matthew Barrett.



Sosa, Camacho-Gonzales, Welch were each charged with Conspiracy to Commit a Felony Crime. Dumke and Gonzalez were each arrested on the same charge and transported to the Gwinnett County Jail. A warrant was obtained for Barrett’s arrest for Acceptance of Benefit, Reward or Consideration by Witness for Changing Testimony or Being Absent. He is currently in custody at the Gordon County Jail with a hold for Gwinnett County.
