New Orleans police vowed to swiftly track down the gunmen who wounded 19 people at a neighborhood Mother's Day parade.

Detectives were conducting interviews, collecting any surveillance video they could find and gathering evidence from the scene where gunmen opened fire Sunday on the parade of hundreds of revelers. 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.

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.
