20 wounded one dead after shooting at Trenton Art All Night event

Twenty people were wounded after gunfire erupted at a New Jersey art event, according to police.

Police in Trenton said that multiple people opened fire at the Art All Night party before 3 a.m. Sunday morning, including a 33-year-old suspected shooter who was pronounced dead.

A 13-year-old boy was the youngest victim, reported in extremely critical condition.

Trenton resident Angelo Nicolo told WPVI that “all hell broke loose” after sounds that he first thought were fireworks.

Police found multiple weapons at the scene of the festival, which went on for 24-hours but was ended after the violence.

“We’re very shocked. We’re deeply saddened. Our hearts ache and our eyes are blurry but our dedication and resolve to building a better Trenton through community, creativity and inspiration will never fade. Not tonight. Not ever,” Art All Night said on Facebook.

It said that none of its staff, volunteers, artists or musicians had been wounded.

Tens of thousands of people were expected to attend the event throughout its day-long run, though it was not clear how many people were there at the time of the shooting.
