Tyrell Dorsey, a 25-year-old African American man, was shot and killed on August 26, 2017, in the 300 block of Royal Avenue in Rockford, Illinois. Officers found Dorsey with a gunshot wound to the head and he was pronounced dead at the scene. No arrests have been announced in his death and the case remains unsolved.

Police treated Dorsey’s killing as one of several related, targeted shootings that night. Three hours earlier Marlon Pendleton, also 25, was shot dead in the 300 block of Underwood Street, and later three people were wounded in the 4100 block of Auburn Street with non-life-threatening injuries. Tracy Barfield Jr., 23, was charged in Pendleton’s murder but was found not guilty by a Winnebago County jury on August 23, 2019; he was not charged in the other shootings from that night.

Does anyone who was in those neighborhoods on August 26, 2017, or who has information about these connected shootings, have details that could help investigators?
