, resigned effective Monday, according to a release from the South Bend Fraternal Order of Police Lodge No. 36.

The FOP cited job-related stress, national media attention and hateful social media comments as reasons for the decision.

“Sgt. O’Neill did his job and was forced to defend his own life from a convicted felon who was armed with an 8-inch hunting knife,” South Bend FOP President Harvey Mills says in the release. “We’re confident that the investigation into the shooting will determine that the action he took was justified based on the law and his training; however, job-related stress, the lawsuit, national media attention and hateful things said on social media have been difficult for O’Neill and his young family.”

South Bend Police Chief Scott Ruszkowski issued a statement Monday evening confirming O'Neill's resignation but offering no further information.

“I can confirm that Sgt. Ryan O'Neill resigned from the South Bend Police Department effective immediately," Ruszkowski's statement reads. "I am in receipt of his resignation letter. I will have no further comment at this time.”

South Bend Mayor Pete Buttigieg released a statement Monday night regarding O'Neill's resignation.

"Our efforts to strengthen trust between law enforcement and community members continue," Buttigieg's statement reads. "We will await results of the independent criminal investigation and apply any lessons learned to our work on the future of the police department and the community."
