BOSTON (WHDH) -
A Boston 18-year-old was arraigned on charges in the weekend killing of a young woman.
Keith Williams, 18, was charged in the death of Dawnn Jaffier in Dorchester over the weekend.
The DA said Williams fired shots from a .357 revolver. He was held without bail and is due back in court on October 14.
Police said they did not believe Dawnn Jaffier was the intended target of a shooting that happened near a parade connected to the annual Caribbean festival in Boston's Dorchester section.
"This is my daughter who's 26 that I'm going to have to end up burying her because someone shot her in the head," said Ian Jaffier.
Jaffier's grieving father fought back tears and asked for help, hoping someone could provide information that would help police figure out who shot and killed his daughter.
"As far as we know this victim is an innocent victim. There's no reason to think anything else," said Supt. Robert Merner of the Boston Police Department.
Jaffier was gunned down Saturday morning on the corner of Charlotte Street and Blue Hill Avenue in Dorchester. A second woman, who was blocks away from where the shots were fired, suffered a minor injury when she was grazed by a bullet.
Investigators said there were extra officers in the area Saturday morning because of the parade and festival. They heard the gunshots and noticed three men running from the area when they responded.
"We had three individuals stopped and detained. Two were questioned and released," said Merner.
The third man, 18-year-old Keith Williams, was arrested and charged with unlawful possession of a firearm, connected to a gun that was also recovered.
"One of our beautiful, productive citizens of Boston was lost to an act of senseless violence," said Chief William Gross of the Boston Police Department.
Jaffier was remembered for dedicating her life to helping others, especially children. The John D. O'Bryant and UMass Amherst graduate was a community partner at the Tobin School in Roxbury and the Hennigan School in Jamaica Plain. She was both a motivator and mentor to the young students.
Her Boston Public Schools family released the following statement:
"Our students called her 'Coach Dawnn.' They looked up to her, and so did we. Dawnn was a loving, generous young woman who made it her mission to improve the lives of others."
Investigators said their forensics and firearms analysis teams were going over the evidence already gathered, including the gun that was recovered, as they tried to figure out who was responsible for the killing.
Boston Police asked anyone with information to contact the BPD Homicide Unit at (617) 343-4470 or 1(800) 494-TIPS.
