Police investigating the death of actor Corey Haim have subpoenaed about 20 doctors.
All of the doctors that have been subpoenaed all practice in the southern California area and had written prescriptions for Corey Haim.
Several of the doctors have already told police that they have never treated or wrote prescriptions for Haim. It is possible that their identities were stolen and used by theives running one of those illegal prescription drug rings. (Photo by Bryan Bedder/Getty Images)
