The Latin Kings street gang in Chicago was run like a business, complete with a CEO, constitution, and its own justice system, according to court filings and undercover FBI recordings.

Federal prosecutors say Fernando King was the “Supreme Inca” of the Latin Kings, sometimes referred to as the gang’s CEO and chief operating officer.

King pleaded guilty to racketeering charges and prosecutors are asking a judge to sentence him to the maximum of 40 years in a federal lockup. Sentencing was postponed Thursday and is now scheduled for next month.

In July 2008, a federal jury convicted him on one count each of drug conspiracy and attempted cocaine distribution, according to the Chicago Tribune.

Chicago’s ABC station WLS-TV reports that Fernando King and the Latin Kings control areas of Chicago’s Little Village neighborhood.

The gang’s constitution was actually required reading for thousands of gang members, according to WLS.  The document explained the group’s hierarchy and rules such as forbidding heroin use.

The group’s constitution details what was expected of disciples, including a willingness to kill or be killed for the good of the gang. The gang even set up a funeral fund to pay the final expenses of slain members.

Federal prosecutors say as many as 10,000 gang members reported to him over a decade.

With the help of  government informants, the FBI recorded King instructing members with rules of conduct and his vision for the organization.

The FBI recordings capture King worrying that bar brawls and drunkenness were ruining the effectiveness of his street gang.

“People look at the Latin Kings as bad people, man. And we only respond, we only respond to negativity. We’re approached in a negative way, we respond in a negative way,” says King on the tapes.
