A 12-year-old girl from New York has died after being struck in the head by a stray bullet inside her Long Island home in a possible case of mistaken identity linked to gang violence.

Dejah Joyner, a seventh-grader and Girl Scout, was eating dinner in her parents' living room in Hempstead Friday when someone fired a single round on the street outside.

The bullet shattered a pane glass window in Joyner's home, struck Dejah in the head and became lodged in her brain.

Joyner was rushed to Winthrop University Hospital in critical condition. On Saturday night, about 26 hours later, she succumbed to her injuries and was pronounced dead at 7pm.

‘Dejah Joyner's life was violently cut short before she even had a chance to live it – this is a heartbreaking tragedy and we will do everything in our power to make sure that the gunman is brought to justice,’ acting Nassau County District Attorney Madeline Singas said Sunday.

At a press conference addressing the incident, acting Nassau Police Commissioner Thomas Krumper vowed to leave no stone unturned in the search for Dejah's killer, whom he called a 'despicable human being.'

Newsday reported that a law enforcement source close to the investigation said police are looking at a possible link between the child's slaying and the ongoing feud between the notorious Bloods and Crips street gangs.

Witnesses reported seeing an older model dark green or black Nissan speeding from the scene on Dartmouth Street moments after the single shot that mortally wounded Dejah was fired at around 5pm Friday.

The unnamed source said that someone living in Dejah’s home may have been the target in an earlier gang-related shooting.

Alex Cruz, a neighbor of the Joyner family, said that someone has shot at their house no fewer than four times, the latest incident being five weeks ago.

Cruz, 29, also claimed that the intended target of the gunman Friday wasn't Dejah but a young man who was seen getting out of the car just moments before the gun went off.

'They miss him and they hit the girl,' Cruz told CBS New York, adding that the same person had been shot at several times before.

On Sunday, Dejah's inconsolable family members, including her mother, Keisha Miles Joyner, and her father, Dameon Joyner, gathered at Antioch Baptist Church in Hempstead for a vigil honoring the slain 12-year-old who loved to dance.

‘My heart is broken, my heart goes out to the family,’ Hempstead Village Mayor Wayne Hall said at Antioch Baptist Church. ‘I'm really sick and tired of being sick and tired.’

Dameon Joyner was seen clutching his late daughter’s stuffed Hello Kitty doll during the somber service. His grief-stricken was sobbing on his shoulder.

Participants in the vigil called for an end to gun and gang violence that has been tearing the neighborhood apart for the past several years and urged the community to help police bring the person who ended Dejah's life to justice.

‘We are not going to lighten up on this,’ Pastor Joe Brown told the congregation, according to New York Daily News. ‘This is going to go on until we find out who did this. You know who you are. So you need to speak up.’
