In the immediate aftermath, police released photos of two people believed to be suspects in the shooting. The second person, who was also identified, was later determined to be a person of interest being sought for questioning. A police spokesperson confirmed Wednesday that only Dumas was facing charges in the case.
Police charged Dumas with three counts of aggravated assault and single counts each of criminal damage to property in the first degree, terroristic threats and acts, reckless conduct and possession of a firearm during the commission of a crime.
He is being held without bond on the aggravated assault charges, online jail records show.
