JACKSONVILLE, Fla. (AP) - Two Jacksonville police officers have resigned after an investigation into the shooting of a toddler wounded as they tried to stop a robbery and carjacking suspect.

Sheriff John Rutherford says he would have fired the officers had they not quit after the results of an internal affairs investigation were released Thursday.

The officers were among five who fired 42 shots as they pursued Jeremiah Mathis on March 26. Mathis was killed, and the 2-year-old boy and his mother were injured. She is suing the officers and Rutherford.

Rutherford says the two officers did not have a clear idea of who was in their line of fire. The police union president says the incident was too fast-paced to second-guess.

The other three officers were cleared.
