Urgent Care Targeted by Corey Haim's Mom

The L.A. County Coroner's Office may investigate several urgent care facilities that prescribed meds to Corey Haim ... law enforcement sources tell TMZ.

Sources say Corey's mom, Judy Haim, told Coroner's investigators that her son had been going to numerous urgent care facilities to score prescriptions.

Judy told investigators she was so frustrated in the last months of his life that she called several of the urgent care facilities herself, inquiring why they would give her son so many pills. She said Corey would often get 60 to 90 pills per visit.

We're told Judy and a friend told investigators they would provide the Coroner's Office with a list of facilities.
