The boy was taken to the hospital in important situation and has been upgraded to secure, KDKA reported, citing the prison criticism.
Police say they do not know of any relationship between the boy and Turner, KDKA reported.
CNN has not been in a position to determine an legal professional for Turner.
“He was with his family, he was standing in line, they had just zipped in for one quick thing,” Cruz instructed KDKA.
The motive stays unclear and the investigation is ongoing, police say.
Detectives from the Major Crimes and Crime Scene items are reviewing the scene, analyzing video proof, and talking with eyewitnesses, the Pittsburgh Public Safety Department posted.
