A school safety agent died of a heart attack after escorting an unruly girl from a school dance in Brooklyn on Friday night. Reports say that Vivian Samuels had to deal with the 12 year old girl's flailing/ pummeling/ striking arms, and that she collapsed afterwards. Safety agents are civilian employees of the NYPD, and Samuels was affectionately known at IS 390 in Crown Heights. The girl has been charged with striking Samuels twice, and will appear in Family Court today; she also faces resisting arrest and harassment charges. The ME's office is still investgating the cause of death, and Samuels' two sons, who are ministers in Brooklyn, are praying for the little girl.
