S3E4 Murder In A Flash

A sudden wave of e-mails and text messages prompts a large group of students to converge on a golf course for an impromptu event. However, the excitement turns tragic when a high school student's lifeless body is discovered as the crowd begins to leave. Investigations lead Horatio and his team to a senior student, son of a prominent defense attorney, who sent out the initial message. The case takes a twist when it emerges that the schoolmaster’s daughter might be involved, and further evidence uncovers that the deceased was involved in an affair with his chemistry teacher.
