Nineteen people were shot in New Orleans on Sunday when gunfire broke out during a Mother’s Day parade. Three of the victims are reportedly in critical condition. New Orleans Police Superintendent Ronal Serpas appealed for public help in finding the shooters.

Ronal Serpas: “We have second lines (of a parade) that occur in the city of New Orleans virtually every weekend at this time of the year. We had a full complement of police officers. It appears that these two or three people, just for a reason unknown to us, started shooting at, towards or in the crowd. It was over in just a couple seconds. Police were everywhere. And we hope that anybody who saw anything will give Crime Stoppers a call.”
