The city's Special Commissioner of Investigation Wednesday released its report on the drowning of a student during a class trip to a Long Island beach, and the Department of Education has fired the Harlem teacher who chaperoned the outing.

Nicole Suriel, 12, was out in the water with about two dozen classmates from the Columbia Secondary School for Math, Science and Engineering during a class trip to a Long Island beach on June 22, when she got caught in the waves. The beach was technically closed and no lifeguards were present.

As a result, DOE officials are firing the girl's teacher, Erin Bailey.

The DOE has demoted Columbia Secondary School's Assistant Principal Andrew Stillman to being a tenured teacher in the public school system and Principal Jose Maldonado-Rivera is being put on probation for two years.

The report said there was a lack of planning by the assistant principal, who had organized the trip, and the principal.

It also said Bailey showed a lack of supervision and that school administrators failed to provide enough chaperones. The other two chaperones were a college student, who was interning, and Bailey's boyfriend, who is a substitute teacher who did not know how to swim.

The investigators said it was unclear whether the chaperones knew that lifeguards were not present.

The report quoted students and chaperones as saying that Bailey said the children could go in the water. Children who did not know how to swim were told by Bailey not to go into the water past their mid-thighs, according to investigators.

Within several minutes, several students, including Nicole, were swept up by a riptide. One student reported he swam to Nicole when she yelled for help, and he said he was pulled under when she grabbed onto him.

Bailey and the college student pulled most of the drowning children onto a jetty. Other beachgoers joined the rescue effort and one was able to grab Nicole by the waist, before being pulled under and losing hold of the girl.

Lifeguards found Nicole about an hour later on the other side of the jetty. She was in cardiac arrest and was unable to be resuscitated.

According to the report, Assistant Principal Andrew Stillman told investigators that the school offered a swimming course in its indoor pool but Nicole had never taken the class.

The report says parents were never given permission slips to sign for the beach trip.

Parents had signed universal permission slips at the beginning of the school year for excursions, but the report found that seven students on the trip did not even have those general slips.

The Nassau County District Attorney's office is also reviewing the findings to determine appropriate reactions.
