Authorities have released video showing one of the possible suspects in a shooting at a Mother’s Day parade in New Orleans on Sunday that left 19 people, including two children, injured.

The grainy surveillance video appears to show the large crowd scattering, possibly from a man dressed in a white shirt and black pants (seen in the foreground of the above picture) with raised hands who may be pointing at the crowd. It’s unclear from the video whether he’s holding a gun or firing shots before he eventually runs away. Some people can be seen falling to the ground.

Authorities are asking for the public’s help to identify the man, one of three potential suspects connected to the shooting.

The FBI says the incident is likely an act of “street violence.”

NBC News:

At least three people were spotted running away from the scene after the gunfire erupted at 1:45 p.m. At least one suspect was described as a man between the ages of 18 and 22.

Police said 10 adult men, seven adult women, a 10-year-old boy and a 10-year-old girl were struck by bullets. The injured children were grazed by the bullets and were in good condition Sunday evening, New Orleans Police spokesman Garry Flot said in a statement. A woman and a man were in reportedly in surgery Sunday evening, but there were no fatalities and most wounds were not life-threatening, police said.

The victims were marching in what is known as a second line parade, a buoyant New Orleans tradition inspired by the city’s iconic jazz funerals: A brass band plays as it marches in the streets, while a lively “second line” of people follows the band, celebrating and dancing.
