Hartford, Conn. ? Following the death of one of pro wrestling’s biggest stars, World Wrestling Entertainment says it is starting random drug testing to detect illicit drugs, steroids and prescription drug abuse among its performers.

Eddie Guerrero, 38, had struggled with drug abuse for years before he was found dead last month in a Minneapolis hotel shortly before a show.

The medical examiner has yet to rule on the cause of death, but Guerrero’s widow has said she was told an autopsy showed signs of heart disease, which she blamed on his past alcohol and drug abuse combined with an aggressive workout regimen.

Stamford-based WWE, whose wrestling programming is among the highest-rated on cable television, said it will announce details of the new testing procedure in the coming weeks. Chairman Vince McMahon told wrestlers last week that the new policy would involve frequent, random tests conducted by an independent agency.
