The number of individuals implicated in the Long Island SAT cheating scandal continues to climb.

Thirteen more suspects marched into the Nassau County district attorney's office on Tuesday, according to a New York Post report. The brings the total number of suspects involved in the scandal to 40, more than double the number initially suspected.

Our investigation has uncovered more than 40 students who either took a standardized test for someone else or paid someone to take it for them, said Nassau County DA Kathleen Rice, according to the Post.

Those implicated in the scandal spanned from several schools in Long Island, including Great Neck North High, North Shore Hebrew Academy and Roslyn. As previously reported by the IBTimes, one of the men arrested, 19-year-old Sam Eshaghoff, can face up to four years in prison, if convicted of criminal impersonation, defrauding and several other charges brought against him.

Eshaghoff and several others reportedly accepted $500-$3,500 payments before taking the SAT and ACT exams for other students. The scandal gained national attention when Eshaghoff was arrested in September for allegedly accepting up to $2,500 from six individuals, for whom he took the college entrance examinations.
