NEW ORLEANS

Video released early today by New Orleans police shows a possible suspect in the Mother’s Day gunfire that wounded 19 people during a neighborhood parade.

The grainy surveillance video shows a crowd suddenly scattering in all directions, with some falling to the ground. They appear to be running from a man who turns and runs out of the picture. The person is wearing a white T-shirt and dark pants. The image isn’t clear but police say they hope someone will recognize him and notify investigators.

Still pictures of the suspect have been posted on YouTube, police said.

Police believe more than one gun was fired in the burst of Sunday afternoon violence — the latest to flare up around a celebration this year — and they have vowed to swiftly track down those responsible. Detectives were conducting interviews, collecting any surveillance video they could find and gathering evidence from the scene. Cell phone video taken in the aftermath of the shooting shows victims lying on the ground, blood on the pavement and others bending over to comfort them.

Police also say the reward for information leading to arrests and indictments in the case is $10,000.

At least three of the victims were seriously wounded. Of the rest, many were grazed and authorities said that, overall, most wounds were not life threatening. No deaths were reported.

The victims included 10 men, seven women, a boy and a girl. The children, both 10 years old, were grazed and in good condition.
