TMZ has learned that the California Department of Justice began serving search warrants Friday in connection with the death of Anna Nicole Smith. One was served this morning at the home of Anna's psychiatrist, Dr. Khristine Eroshevich, and we're told Howard K. Stern was actually there at the time!

We're told that eight warrants were served altogether, and may be connected to the Department's investigation of Dr. Eroshevich. Sources say the warrants were served at several businesses connected to Anna's doctors and at a storage facility.

As TMZ first reported, the Medical Board of California is investigating Eroshevich, who ordered a virtual pharmacy of drugs for Anna, five days after her son Daniel died.

UPDATE: We're told the DOJ will hold a press conference at 11:00 AM. Stay tuned!
