Authorities have made a second arrest stemming from a shooting at a 24-hour arts and music festival in Trenton

Mercer County prosecutors say Davone White is facing three weapons charges. The 26-year-old Trenton resident was among nearly two dozen people wounded in the shooting, and he remained hospitalized Tuesday.

About 1,000 people were attending the Art All Night Trenton festival that showcases local art, music, food and films when shots rang out early Sunday. Authorities have said several neighborhood gangs had a dispute, and multiple suspects began shooting at each other, with police returning fire.

Police shot and killed one suspect, 33-year-old Tahaij Wells. White and 23-year-old Amir Armstrong, who also faces weapons charges, were among the 22 people injured.

Trenton’s leaders joined law enforcement officers Tuesday at Friendship Baptist Church to discuss the shooting. Many say that the arts festival must continue in the future.

“We will make the event bigger, brighter, safer and better. I believe that will happen,” says Trenton Mayor Eric Jackson.

Authorities are also looking into reports that a Hamilton Township teacher posted a warning on social media that a shooting would happen at the festival. Investigators are looking into the validity of those posts and say that they want to speak with this teacher.

“She had gone to North Carolina on vacation,” Mercer County Prosecutor Angelo Onofri says, adding that the teacher now has an attorney.

Suspects Wells and Armstrong both had criminal histories, according to investigators. Local activist Darren Green says he spoke with Wells, who was recently released from prison, just a couple weeks ago.

“He was standing there and I was talking to him about possible jobs and opportunities and working and life. And he just was in a troubled state,” Green says.

Onofri says that the shooting may have been retaliation from a previous shooting.

Art All Night Trenton’s organizer tells News 12 New Jersey that he is distraught over the whole situation. He says that artists should not try to come by to claim their artwork because the location is still being considered a crime scene.
