S2 E9: When a young gymnast is found dead, her world-renowned coach (guest star Philip Casnoff) becomes a prime suspect as his rigorous demands of his students are discovered. Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) soon find that the girls also vie for the attention of a wealthy benefactor (guest star Armand Schultz) whose interest in the young athletes does not appear to be purely philanthropic.
