The teen accused of shooting a 16-year-old girl outside her Queens high school has a rap sheet that includes a pair of armed stickups and a violent mugging that left the victim badly beaten, The Post has learned.
Caolynn Griffin-Bratton, 16, was busted in April for a March 19 incident in which a 14-year-old boy was left with an arm broken in two places from being viciously assaulted and robbed, law enforcement sources said Thursday.
“He beat the crap out of his victim,” one source said.
Griffin-Bratton was also arrested along with two cronies for allegedly using a silver handgun to steal a bicycle, an Apple iPad and an iPhone 8 during two robberies on July 11, sources said.
One of those victims was 15 years old, sources said.
All of the incidents took place in Queens, sources said.
In addition, Griffin-Bratton was charged with swiping several items from a bodega in the Rockaways, sources said.
Online court records don’t show any pending adult charges against him, but a source said the case involving the 14-year-old boy who was beaten and robbed was pending.
The teen was charged Thursday with attempted murder, two counts of assault, reckless endangerment and criminal possession of a weapon in a pair of shootings on Monday afternoon, sources said.
Those incidents include the wounding of 16-year-old Ashley Amoorgan, who was hit in her left shoulder by a stray bullet across the street from the New Dawn Charter High School II in Jamaica shortly before 4 p.m.
About an hour earlier, Griffin-Bratton and two other teens were also involved in a shooting on a Q113 bus, sources said.
No one was injured in that incident.
Detectives have tied the shooting of Amoorgan to Saturday’s stray-bullet slaying of 14-year-old Aamir “Buddy” Griffin, who was shot in the neck while playing basketball at the Baisley Houses, NYPD Chief of Detectives Dermot Shea said Wednesday.
Bratton-Griffin also lives in the Baisley Houses, sources said, but it was unclear if he’s related to the dead teen.
The NYPD has blamed both shootings on a running conflict between two rival groups of teens, with sources saying members of the Mac Baller Brims street gang comprised one side.
During an unrelated news conference Thursday, Shea said two unidentified teens, ages 16 and 17, had also been arrested in the shooting on the bus and were expected to be charged.
Shea said it was unknown if they would be prosecuted as adults.
