Hours after a deadly shooting at the Art All Night festival in Trenton left one dead and 22 injured, Gov. Phil Murphy spoke during a Sunday service at the Galilee Baptist Church in Trenton, offering words of encouragement and prayers to the community.

Murphy - who signed some of the strictest gun laws in the nation just four days before the violent shooting - reminded Trentonians during the mass that through faith and community, "we can rise above this."

"It's yet another reminder of the senseless gun violence, even having signed six stringent gun laws last week," Murphy said at a press conference following the mass. "We know we're getting stronger and better but we're a long way from getting rid of this senselessness."

In the early hours of Sunday morning, gunfire erupted at the Roebling Wire Works Building. A suspected gunman, a 33-year-old male, was killed by police, Mercer County Prosecutor Angelo Onofri said.

Police said another suspect is in custody.

"Sounds like it was some sort of dispute -- We will bring the full weight of law and justice against them. As it related to Art All Night -- it tells me we need it now more than ever before. Events that will bring the community together," Murphy said.

Seventeen of the 22 injured victims were shot, including a 13-year old boy who is in extremely critical condition, officials said.

After speaking during the service, Murphy made a brief visit to Capital Health Regional Medical Center, where many of the shooting victims were taken.

Art All Night was celebrating its 12th year as a Trenton tradition featuring art, music and film. About 1,000 people were at the 24-hour event when the gunfire erupted.

The investigation is ongoing, officials said.
