Travis McCoy, 26, and Adriana Smith, 28, are both charged with one misdemeanor count of child endangerment. McCoy is charged with an additional felony count of filing a false complaint or report to 911 and Smith is charged with an addition felony count of obstruction of justice for destroying evidence.
Chicago police said the shooting began as a domestic situation inside a home inside the North Eastwood Shores Apartments in the 800-block of West Eastwood Avenue around 7:30 p.m.
Police say McCoy and Smith were fighting over a gun and the gun went off. According to police, the bullet ricocheted inside the apartment and struck the boy in his head, but did not penetrate the skull.
McCoy ran with the baby to Weiss Hospital, where the baby was transferred to Lurie Children's Hospital. The baby remained in serious condition Tuesday morning, police said.
Police said McCoy told them he was standing outside when he was shot at by individuals on the street at Clarendon and Leland avenues, but police said no shooting took place there.
Both McCoy and Smith are due in court Thursday.
