HOUSTON, Texas — 11 felons handed federal prosecutors the evidence they needed to send them back to prison on firearms charges.

Prosecutors say the men — all of Houston, and all convicted felons — shot a rap video at Northeast Houston's Lakewood Park on March 28, 2018, while brandishing loaded firearms. That video, which promoted gangs in Houston, was uploaded to YouTube, released on May 20, 2018, and promoted by

At the time of the video's production, police received a 911 call to the park and, upon arrival, discovered a majority of the group had fled the area. Eight loaded firearms were subsequently located abandoned at the park.

"From the video, authorities were able to identify each person who was in possession of a firearm by comparing each gun recovered at the scene to the ones they held in the video," stated a press release from the U.S. Attorney's Office in the Southern District of Texas.

The final defendants were sentenced in the case earlier this week on charges for unlawful possession of a firearm by a convicted felon.

The lead rapper in the video, 30-year-old Warren Brown II, also known as NFL Cartel Bo, was sentenced to 78 months in federal prison. 30-year-old Keithric Lewis was sentenced to 60 months. 36 month sentences were handed to 31-year-old Ivory Vershone Brown and 37-year-old Jerrell Grant. Four men, 31-year-old Joshua Amos, 34-year-old Roland Labome, 30-year-old Garrett Winn, and 26-year-old Devonte Haynes were sentenced to 30 months. 22-year-old Kenneth Fontenot and 30-year-old Marces Randolph were sentenced to 24 months and 33-year-old Frenton Price was sentenced to 20 months.

"With the exception of Winn, Amos, Price, Randolph and Labome, all have been and will remain in custody pending transfer to a U.S. Bureau of Prisons facility to be determined in the near future," according to the U.S. Attorney's Office. "The others had been previously released but were permitted to voluntarily surrender to a U.S. Bureau of Prisons facility to be determined in the near future."

The Bureau of Alcohol, Tobacco, Firearms, and Explosives and the Houston Police Department conducted the investigation. Assistant U.S. Attorneys Britni Cooper and Lisa Collins are prosecuting the case.
