According to court documents, the Lowrider Street Gang was a local gang that operated mostly out of Davenport. The purpose of the gang was to distribute drugs, obtain money, and maintain respect in the neighborhood. Lowriders were expected to retaliate against their perceived rivals, such as the Latin King and West Side Mafia street gangs. The Lowrider Street Gang was organized by tiers of memberships; the highest rank was referred to as the “Shot-Callers,” then the middle-level ranking was “Older Homies.” The lowest level were the “Shortys,” who typically consisted of younger members, including juveniles, who had not yet put in “work” to gain a higher ranking. Lowrider members define work as dealing drugs, conducting robberies and shootings, or otherwise assaulting rivals. The Lowriders conducted their affairs through a series of rules and policies and enforced discipline through a system of violations in which members physically beat those members of the gang who violated the rules. The Lowriders also initiated new members through the practice of causing them to endure physical assaults conducted by members of the gang at various gang-related gatherings.

“I am thankful and proud of the courageous work our officers do in the City of Davenport every day,” stated Davenport Police Chief Paul Sikorski. “The amount of work by our investigators that went in to putting together this very complex case has been noticeably impactful in Davenport and in the Quad Cities. The unique and critical partnership we have with our prosecutors from the United States Attorney’s Office and our Quad Cities area law enforcement agencies, combined with the pure determination and commitment by everyone involved with this case, has made Davenport a safer place.”

“Whether by individual defendants, or by criminal street gang, violent crime has no place in communities like Davenport,” stated United States Attorney Richard D. Westphal. “The crimes committed in furtherance of this criminal enterprise, that included attempted murder, drug trafficking, transferred firearms to juveniles, possession and use of firearms, were extremely dangerous. We are grateful to the Davenport Police Department, and our state and federal partners, for the hard work to successfully prosecute these members of the Lowriders street gang.”

United States Attorney Richard D. Westphal, of the Southern District of Iowa made the announcement. The case was investigated by the Davenport Police Department with assistance from the Federal Bureau of Investigation, Drug Enforcement Administration, Iowa Division of Criminal Investigations, Bettendorf Police Department, Moline Police Department, and the Scott County Sheriff’s Office.
