A woman who investigators believe may be connected to a fatal shooting in Waterloo has turned herself into authorities.

Earlier this week, officials identified 25-year-old Marcus Sykes as a person of interest in a May 15th shooting that killed 23-year-old Dayton Matlock and injured two women. At the time, authorities said they believed Sykes was hiding out in the Des Moines area with 23-year-old Shireca Wilson, who was wanted for crimes unrelated to the shooting.

According to Des Moines police, Wilson turned herself into Iowa City authorities on Tuesday and she has since been transported to the Polk County Jail. Authorities had issued warrants for Wilson's arrest, charging her with second-degree burglary and willful injury. Wilson has not been charged in connection with Matlock's death.

While investigating the homicide, Waterloo police discovered that Sykes was in possession of a firearm around the time of the shooting. There is an active warrant for Sykes' arrest, charging him with felon in possession of a firearm.

As of Thursday, officials were still searching for Sykes. He's described as a 5'9", 135-pound black male with multiple tattoos on his body.

Anyone with information on where Sykes and Wilson might be is asked to call 911 or contact Waterloo police at 319-291-4340.
