Two Davenport men have been convicted of racketeering-related and gun charges, according to a news release from the U. S. Attorney’s Office – Southern District of Iowa.
The two were convicted by a federal jury after a week-long trial related to incidents they allegedly carried out as members of the Davenport-based Savage Life Boys (SLB) street gang in 2016 and 2017.
According to a release from the U.S. Attorney’s Office for the Southern District of Iowa, Najawaun Marcus Quinn, 26, was convicted of:
- Assault with a dangerous weapon in aid of racketeering
- Using and carrying a firearm during and in relation to a crime of violence
- Felon in possession of a firearm.
Dimetri Alexander Smith, age 30, was convicted of:
- Two counts of assault with a dangerous weapon in aid of racketeering
- Two counts of using and carrying a firearm during and in relation to a crime of
violence.
According to court documents and evidence presented at trial, as members of Savage Life Boys (SLB), a Davenport-based street gang in 2016 and 2017, Quinn and Smith were involved in several shootings, including incidents at:
- A residence on the 5400 block of North Division Street in October 2016
- NorthPark Mall in January 2017
- Centennial Park in April 2017.
The shootings allegedly were part of a feud with a rival gang and in response to perceived disrespect to the SLB gang, according to federal documents.
Police allege Quinn and Smith also were involved in a February 2017 homicide at the Hotel Davenport, court documents show.
Another SLB member, Darion Gardner, 27, of Davenport, pleaded guilty to racketeering-related charges and was sentenced to 37 1/2 years in prison.
The release says that Quinn and Smith, who allegedly committed these acts to maintain or increase their position in the SLB gang, will be sentenced at a later date.
