A Georgia teacher has been identified as the second person killed over the weekend when a small plane crashed in the ocean off the Hamptons.

Dr. Jennifer Landrum, a special education teacher at Thomson High School, was one of three victims who died in the 11 a.m. Saturday plane crash, the McDuffie Board of Education and Schools Superintendent Mychele Rhodes announced on Facebook.

“Dr. Landrum was a valued member of the McDuffie County School System,” Rhodes said in the statement. “Dr. Landrum will certainly be missed. Please keep her family in your thoughts as they go through this most difficult and trying time.”

The Georgia school’s principal, Trevor Roberson, told WRDW: “We all saw her Wednesday. Wednesday was the last day we had school and everyone saw her on Wednesday and for us to come back on Monday and know we won’t see her again, a huge shock.”

The seven-seat, twin-engine Piper PA-34 that Landrum was in — along with 41-year-old Raj Persaud of Waterbury, Connecticut, and another unidentified man — went down about a mile off Quogue, according to New York state police.

The plane, owned by Persaud, had been flying from Danbury, Connecticut, to Charleston, South Carolina, when it lost radio contact with air traffic controllers prior to the crash, officials previously told The Post.

The Federal Aviation Administration and the National Transportation Safety Board are investigating the crash.
