Erin Andrews' attorney says the ESPN reporter and “Dancing with the Stars” contestant has been the subject of death threats since the end of March.

Marshall B. Grossman says several threatening e-mails regarding Andrews have been sent to sportscaster Dan Patrick starting in September. These e-mails, “until very recently, were of a sexual nature but then turned violent,” Grossman told CNN.

In March, an Illinois man was sentenced to two and a half years in prison for secretly recording images of Andrews in the nude.
