Police said the 1-year-old suffered a gunshot wound to the head.
According to a press release from Pittsburgh Public Safety, police transported the child to the hospital. The press release said, “With a police sergeant driving, two police officers held the baby in the backseat and worked to control the bleeding. The child arrived at the hospital in critical condition.”
The child later died of his injuries.
According to investigators, the shots were fired outside and traveled through a window and then two walls before hitting the child.
No arrests have been announced.
Early Tuesday morning, Mayor Bill Peduto tweeted about the shooting, writing, “Senseless gun violence must end. Another innocent life has been stolen. We will work endlessly to find the actor and hold them accountable for this horrific crime.”
