Buttigieg is scheduled to debate on June 27.
The St. Joseph County Metro Homicide unit is investigating the death of at least one person, according to the tweet.
Buttigieg: "I'm not asking for your vote".
O'Neill's body camera and dashboard camera were inactive during the incident. "And I accept responsibility for that".
The Monday morning Fox News crew labeled Buttigieg "weak" and "overwhelmed" by the primarily black attendees at a South Bend town hall Sunday.
Crime has been a long-term problem in South Bend, and this incident highlights Buttigieg's failure to address the problem during his seven years as mayor.
"I don't know if it's smart or not. It's my job to face it".
Buttigieg held the town hall at Washington High School in South Bend alongside Police Chief Scott Ruszkowski.
Others in the audience heckled Buttigieg for campaigning days after the shooting.
There is no contradiction between respecting the risks that police officers take every day in order to protect this community, and recognizing the need to overcome the biases implicit in a justice system that treats people from different backgrounds differently, even when they are accused of the same offenses.
Anger surrounding the police shooting came from both black and white residents of South Bend, who demanded changes to the police department.
Lwan Easton, a 37-year-old South Bend resident who attended the town hall, said the city needs to unite, but said he didn't expect much going into the town hall.
"I don't want to seem defensive, but we've taken a lot of steps; they clearly haven't been enough, but I can not accept the suggestion that we did nothing", he said.
