South Bend police officer who fatally shot black man resigns

South Bend Mayor Pete Buttigieg shares a moment with Shirley Newbill, the mother of shooting victim Eric Logan.

(CNN)An Indiana police sergeant who shot and killed a black man suspected of breaking into cars has resigned from the South Bend Police Department, Chief Scott Ruszkowski told CNN on Monday.

The shooting roiled the Indiana community, drawing attention to years of racial tension between the South Bend Police Department and the city's African American residents. It has also provided a glimpse into presidential candidate Pete Buttigieg's leadership as South Bend's mayor.
Police said Ryan O'Neill shot Eric Jack Logan on June 16 while Logan was breaking into cars with a knife in his hand.
Logan's family disputes the account involving the knife. They filed a federal lawsuit in June against the city and the officer, accusing O'Neill of using excessive force and targeting Logan based on his race.
    Demonstrators protest the shooting death of Eric Logan outside of the South Bend Police Station after his funeral on June 29.
    "We're confident that the investigation into the shooting will determine that the action (O'Neill) took was justified based on the law and his training," said Harvey Mills, President of the South Bend Fraternal Order of Police.
    However, job-related stress, the media attention and hateful social media comments have been "difficult" for O'Neill and his family, Mills said. O'Neill is also the subject of a special prosecutor investigation, a civil lawsuit and potential departmental discipline, Mills said.
    "These fights are just too much for Sgt. O'Neill and his family to undertake right now," Mills said. "Resigning will allow him to focus on these challenges, as well as assist his wife with their three children, one of whom is a newborn."
    Mill said that O'Neill was "forced" to defend his life from a convicted felon who was armed with an eight-inch hunting knife.
