Sources: Police believe they have gang kingpin's killer in custody

Chattanooga police investigators work the crime scene where Jumoke Johnson, 23, and Christopher Woodard, 20, were killed on the 2100 block of E. 12th Street.

The inmates beat Jermichael Brooks so badly that officers had to guide the nearly blind 23-year-old man into a federal courtroom Friday.

Before the judge, Brooks pleaded not guilty to drug and gun accusations - but the charges assure he sits in jail while police build a high-profile murder case against him.

Investigators think Brooks killed well-known gang leader Jumoke Johnson, 23, and Christopher Woodard, 20, on Jan. 20, shooting them from the back seat as they rode in a car together, sources said.

Brooks hasn't been charged in the double homicide, yet, but three sources told the Times Free Press that Brooks is the prime suspect in the slaying, which may have been motivated by a cheating girlfriend.

The sources, who spoke on the condition of anonymity, said Woodard may have been having an affair with Brooks' girlfriend before the slayings.
