Police have arrested a 28-year-old man in relation to a shooting that occurred at a homeless encampment under the Water St. Bridge in Concord on Saturday, June 7.

Trenton McDonald, who was taken into custody on Friday by the Farmington Police Department and other regional authorities, faces the following charges: armed robbery, first and second degree assault, reckless conduct, felonious use of a firearm, felon in possession of a dangerous weapon, armed career criminal and criminal threatening involving a firearm.

McDonald was transported to the Merrimack County House of Corrections, where he was held on preventative detention while waiting for arraignment at Concord District Court on Monday morning at 11 a.m., according to a press release from the Concord Police Department. The investigation is ongoing, and the police said they expect to make additional arrests.

Police first received word of the shooting when a caller phoned them at 7:25 a.m. on Saturday, June 7 to report that a man had been shot. Concord Police responded to the Water Street Bridge and quickly located the victim, a 30-year-old male who had been living in an encampment under the bridge and had a gunshot wound in his back. Police took him to Concord Hospital with life-threatening injuries.

Concord Police believe the shooter, an male sus pect, fled the  scen e on foot. Authorities had received a report that the shooter was accompanied by two accomplices, one male and one female, and that all three ran from the area after the shooting, according to a press release. The same day as the shooting, Concord Police officers, assisted by State Police troopers, remained in the area, near the railroad tracks where Route 3 splits from South Main St. Police fanned out and questioned multiple people, but they made no arrests until McDonald on Friday, June 13.
