DAVENPORT, Iowa – A Quad Cities man was sentenced April 23, 2024, to seven years in federal prison for possessing a firearm as a felon.

According to public court documents, Marveon Dashawn Jovan Williams, 27, in May 2022, Davenport Police responded to a call for a gunshot victim in a vehicle. Upon arrival on the scene, the victim was located in the driver seat of a vehicle, with a gunshot wound to the head. Several firearms, including one located on the passenger side, and one located on the sidewalk outside the passenger side of the vehicle were recovered. A cell phone belonging to Williams was also located on the scene. Witnesses described a shootout between two different vehicles. A male, matching Williams’ physical description was seen possessing the firearm that was dropped on the sidewalk and recovered by police and fleeing the crime scene. Video surveillance footage of the scene showed Williams fleeing the area and then changing his clothing in a nearby wooded area. The discarded clothing was recovered by law enforcement and tested for DNA. DNA belonging to Williams was located on the clothing recovered from the wooded area.

After completing his term of imprisonment, Williams will be required to serve three years of supervised release. There is no parole in the federal system.

United States Attorney Richard D. Westphal of the Southern District of Iowa made the announcement. This case was investigated by Davenport Police Department.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.
