A candlelight vigil was planned Sunday night for the 15-year-old boy shot by police deputies while brandishing a toy gun in his middle school.
Christopher Penley, of Winter Springs, Florida, was officially pronounced dead at 4:57 a.m. (0957 GMT) Sunday, the Seminole County Sheriff's Office said in a statement posted on their Web site.
Penley had been brain dead since about 10:30 a.m. Saturday morning, but was kept alive so his organs could be harvested, said Mark Nation, a lawyer for Penley's parents.
Penley was accused of taking a toy gun to Milwee Middle school Friday that closely resembled a 9mm handgun. After a classroom scuffle in which he struggled with another boy over the gun, he was cornered by sheriff's deputies and a police elite unit in a school bathroom, authorities said.
Family and friends continued to mourn the boy, who they say was emotionally troubled, reportedly bullied at school and had run away from home several times. His vigil was scheduled for 6 p.m. (2300 GMT) at Landmark Community church.
