Dayton Matlock was 23 and described as someone who loved fishing and the outdoors. In the early morning hours of May 15, 2021, Waterloo police responded to a shooting in the 1400 block of Grant Avenue and found Dayton in an alley; he had died from a gunshot wound. Two women, 39-year-old Bobbi Lee of Waterloo and 30-year-old Shanayia Hamer of Des Moines, suffered non-life-threatening gunshot injuries.

Waterloo investigators interviewed witnesses and developed leads. In June 2021 two people were publicly named as persons of interest: 23-year-old Shireca Wilson and 25-year-old Marcus Sykes. Wilson later turned herself in in Iowa City and was not charged in Dayton’s death. Authorities say Sykes was believed to have had a firearm around the time of the shooting; a warrant for felon-in-possession was issued and he was apprehended in March 2022 on separate gun charges.

No one has been charged with Dayton’s murder and the case remains unsolved. Anyone with information is asked to contact the Waterloo Police Department at 319-291-4340. Does anyone have information about Dayton, his routines, or that night on Grant Avenue?
