(AP) — Three members of the Black Gangster Disciples and Vice Lords have pleaded guilty to federal drug trafficking charges, court records show.

Christopher Antonio Bolton, 31, Marquis Collins, 29, and Edward Montrell “Black” Brown, 30, all of Jackson County, are each facing up to 20 years in prison and fines of up to $1 million at their July sentencing hearings.

All three pleaded guilty last week to distributing cocaine.

The trio is among 15 gang members arrested in February following a two-year joint investigation into meth and powder and crack cocaine trafficking in South Mississippi.
