(CNN) — Lab results are back in the case of a teenager who died in a police shooting in St. Louis last week, and they show gun residue on the clothing and body of Vonderrit Myers, authorities said Tuesday.
The residue was found on Myers’ shirt, jeans and hand, according to a release from St. Louis police.
Its presence on his hand could mean that he discharged a firearm, was near a firearm when it went off or that Myers touched something with gun residue on it, police said. People shot at close range could also have residue deposited on their hands.
Myers was fatally shot Wednesday by a St. Louis officer, who was off-duty but wearing his uniform while moonlighting for a security company. Police have said the teenager fired a pistol three times at the officer.
The shooting sparked street protests, with residents pointing out similarities to the August killing of Michael Brown in nearby Ferguson, Missouri.
Myers and Brown were both 18 and black and killed by white police officers. However, unlike Myers, authorities say Brown was not armed.
Myers was struck by seven or eight bullets, St. Louis city Medical Examiner Dr. Michael Graham said last week.
Police say the officer fired his pistol 17 times.
“All but one gunshot wound were to the lower extremities,” Graham said. “The one fatal wound was to the head.”
