Agents from the California Department of Justice on Friday raided the Studio City home of Dr. Khristine Eroshevich, the psychiatrist who was treating Anna Nicole Smith before her death.
“There were about six cars and some men walking around with guns,” a resident who lives on the street tells PEOPLE.
A rep for the federal Drug Enforcement Agency confirms that a raid happened with the DEA assisting. The officials served Eroshevich with a search warrant but no arrests have been made, according to the DEA rep, Jose Martinez.
It was reported in April that Eroshevich was under investigation by authorities who were looking into Smith’s death. She died of a drug overdose last Feb. 8.
Eroshevich was the doctor who authorized the 11 prescription medications discovered in Smith’s Florida hotel room the day she died. The doctor was being investigated by the California Medical Board and the probe “involved Anna Nicole Smith,” a rep confirmed to PEOPLE in April.
Eroshevich is a Los Angeles-based psychiatrist and friend of Smith’s who had traveled with her to Florida.
CNN reported that Smith’s former companion, attorney Howard K. Stern, was at the Eroshevich home when authorities arrived. His presence was explained because his dogs were at the house, and he had just returned to collect them.
California Attorney General Jerry Brown said at a press conference Friday that he would not disclose the subject of the search warrants because that could jeopardize the investigation, even these eight months after the death of Smith.
