According to the Okaloosa County Sheriff’s Office, 18-year-old Mark Williams of Crestview had been shot at least seven times with three different weapons.

FORT WALTON BEACH — The former head of a local gang and marijuana distribution operation has been sentenced to 30 years in prison for his role in the 2015 death of a Crestview teenager, State Attorney William Eddins announced Monday.

Marvin Andrew Wilkins, who had headed a criminal enterprise then known as the “Money Mafia,” entered pleas Monday on charges of second-degree murder, racketeering and conspiracy to commit racketeering. The plea had called for a sentence ranging between 30 years to 45 years, according to a news release from Eddins’ office. 

Wilkins, 37 years old at the time of the shooting, had originally been charged with two counts of racketeering and a single count of first-degree murder in the death of 18-year-old Mark Williams of Crestview.

The state attorney’s office announced in January that it would not seek the death penalty against Wilkins, citing concerns about their ability to prove the required “aggravating circumstances” and concerns about the “muddled” state of Florida’s death penalty law, which had been called into question by both the Florida Supreme Court and the U.S. Supreme Court. 

According to the Monday news release from the state attorney’s office, Wilkins believed that Williams was passing information about the “Money Mafia” to a rival gang, and on Jan. 20, 2015, he sent three people to Crestview to pick up Williams and bring him to a hotel room on Okaloosa Island. 

“Wilkins told them to bring Williams back to the hotel room, ‘but if you can’t, do what you have to do,’ ” according to the news release. En route from Crestview to Okaloosa Island, the man driving the car, then-20-year-old Bernard Nunnally of Crestview, pulled the vehicle over and shot Williams, the news release noted.

The other two people in the car, then-20-year-old Nijajuan Russell of Ozark, Alabama, and then-17-year-old Erich Justice, also shot Williams and were charged with first-degree murder and racketeering in his death. According to the Okaloosa County Sheriff’s Office, Williams had been shot at least seven times with three different weapons.

Williams’ body was discovered the day after the fatal shooting on the side of State Road 85. 

Justice entered a plea in connection with his involvement in Williams’ death and was sentenced to a 25-year minimum mandatory prison sentence. Nunnally also entered a plea and has been sentenced to 45 years in state prison. Russell will be scheduled for trial at a later date, according to the state attorney’s office.
