Blake D. Mixon
Baton Rouge resident Blake D. Mixon, 31, is serving a 40-year prison term at the U.S. Penitentiary at Coleman, Fla. The Federal Bureau of Prisons currently estimates Mixon will be released from the high-security facility in May 2044, when hewill be 63.
State and federal court records in Baton Rouge show Mixon’s long life of imprisonment began after he was indicted in state court in July 2000. He was 19. In November 2001, Mixon pleaded guilty to possession of Diazepam with intent to distribute. He also pleaded guilty to possession of a firearm during a drug crime. He was sentenced to five years in state prison.
Mixon was released on parole in January 2005.
By March 2008, Mixon was indicted by a federal grand jury for drug conspiracy, possession with intent to distribute methamphetamine, possession with intent to distribute Ecstasy and possession by a convicted felon of both a .40 caliber semiautomatic pistol and a 7.62 mm rifle.
On July 30, 2008, Mixon signed an admission that he resumed selling Ecstasy in February 2005, the month after his release from the Louisiana State Penitentiary at Angola.
Mixon also admitted selling cocaine in January 2006. He said he began selling methamphetamine in September 2006. And he admitted that he used his illegally purchased assault rifle in January 2007 to rob his methamphetamine supplier of her drugs and cash.
Baton Rouge resident Lonnie Poydras, 30, admitted he was part of an armed three-man crime group in April and May 2001. The trio robbed a grocery store, took a deputy sheriff’s pistol and cell phone at gunpoint, stole an LSU student’s 1991 Oldsmobile Royale, and carjacked a 1996 Chevrolet Cavalier from three other men. They also shot to death Demetrius White at a canal bridge on a service road of Florida Boulevard.
Poydras was 18. He pleaded guilty to conspiracy to commit armed robbery, testified against a co-defendant who Poydras said fired the fatal shot, and was sentenced to 10 years in prison, court records show.
But Poydras was a free man by May 2009, when he was stopped on North Harrell’s Ferry Road by two Baton Rouge police officers. One of the officers later signed a report that said Poydras granted permission to search his Chevrolet Tahoe, in which a .40 caliber pistol was discovered next to the driver’s seat.
Turned over to federal authorities for prosecution, Poydras was convicted at trial on a charge of illegal possession of a firearm by a convicted felon. In April 2011, he was sentenced to six years in federal prison, but won an appeal on grounds that jurors should not have heard some witness testimony about his character. A new trial is scheduled for March 28.
Michael W. Young
Michael W. Young, 28, of Baton Rouge, was just a teenager in 2003, when he pleaded guilty in 19th Judicial District Court to charges of simple burglary and attempted simple burglary. At 19, he was sentenced to six years in prison.
In January 2009, Young pleaded guilty in state court to attempted possession of marijuana and was sentenced to six months in Parish Prison.
But, in March 2012, Young pleaded guilty in federal court to charges that he was a felon in possession of both a Chinese model SKS 7.62 mm rifle and a 9 mm pistol. He also pleaded guilty to possession of marijuana with intent to distribute the illegal substance.
In August, Young was sentenced to 15 years in federal prison, a term that was equaled by only one other felon convicted in Baton Rouge federal court last year for possession of a firearm.
The Federal Bureau of Prisons assigned Young to the U.S. Penitentiary at Beaumont, Texas, where he is scheduled for release in March 2025.
In four separate cases in June 1997, Baton Rouge resident Gregory Mumphrey pleaded guilty in 19th Judicial District Court to three counts of simple burglary and one count of possession of stolen things. At 18, he was sentenced to seven years in state prison.
Mumphrey, 34, was out of state prison by November 2006, when he pleaded guilty to possession of Ecstasy and was sentenced to 10 months in East Baton Rouge Parish Prison.
But Mumphrey lost a huge chunk of his free time last year after he pleaded guilty in Baton Rouge federal court to possession by a convicted felon of a .40 caliber handgun. In November, he was sentenced to 15 years in federal prison.
Like Blake Mixon, Mumphrey is incarcerated at the U.S. Penitentiary at Coleman, Fla. The Federal Bureau of Prisons estimates Mumphrey will be released in May 2025.
Kenneth R. Rayborn
Livingston resident Kenneth R. Rayborn, 61, was the only person acquitted among 47 charged in Baton Rouge federal court in 2008 as felons in possession of firearms.
Rayborn pleaded guilty in 1999 to one federal charge each of unauthorized acquisition of food stamps and illegally dealing in firearms. He was sentenced to 21 months in federal prison for that conviction.
After his release under post-prison supervision, he was found in violation of the rules of that supervision and returned to federal prison for nine additional months.
In March 2008, detectives of the Livingston Parish Sheriff’s Office used two warrants to search Rayborn’s grocery store, adjacent house and truck. The detectives discovered three shotguns, a .22 caliber semiautomatic rifle and 115 pills containing hydrocodone, a highly addictive controlled substance.
The case was referred to the U.S. Attorney’s Office in Baton Rouge, but a jury acquitted Rayborn on charges that accused him of being a convict in possession of firearms, as well as a person in illegal possession of hydrocodone.
“He had a prescription,” Rayborn’s attorney, Assistant Federal Public Defender Mark Upton, said in a recent interview.
As for the three shotguns and .22 caliber rifle, Upton said Rayborn’s son testified that he left those weapons at his father’s house after Hurricane Katrina struck Louisiana in 2005. Upton said the son moved to Tennessee for a job.
“The jury believed the son, who was a very credible witness,” Upton said.
