If you in any way examined or treated Michael Jackson over the past decade, chances are you've been in contact with law enforcement recently.

Cherilyn Lee, the nurse and nutritionist who says that the King of Pop once begged her for propofol, confirms to E! News that the Los Angeles County Coroner's Office was at her office Wednesday to pick up Jackson's medical records.

"Before the Fourth of July they were contacting me," Lee tells us. "They were initially telling me thank you because it helped with their investigation."

The coroner's visit to Lee's office today came as two LAPD detectives, Houston police and Drug Enforcement Administration agents executed a search warrant at the Houston offices of Dr. Conrad Murray, the cardiologist employed privatedly by Jackson at the time of his death.

Lee reiterated that she never administered the anesthetic propofol—or any other drug—to Jackson when he was under her care.

"He didn't take any medications from me, I'm just nutritional," Lee told E! News today. "When it switched over to medication, especially that particular medication, I told him—I only deal with nutrition."

She said that she last spoke to Jackson on June 21, four days before his death, when a member of his entourage called her to alarmingly report that Jackson felt cold on one side of his body and hot on the other.

"I received a call from his staff on Father's Day asking if I could come see him right away," says Lee. "I could hear Michael in the background. He sounded very anxious when he was making the statement that one side of his body was real hot and one side of his body was very cold. I said he should go into the emergency room. That's the last time I spoke to him."

The last time she saw him was in April—and she didn't see any signs of drug abuse then, Lee says.

"Anyone who is abusing drugs is not going to have normal lab results," says Lee of the records she handed over to the authorities. "I didn't see...signs, nothing."

"I did an exam of his body, and he was fine," she added. "There were no track marks."

A source familiar with both autopsies that were performed has confirmed to E! News that there were needle marks on Jackson's neck and arms when he died. A coroner's source says a potentially lethal amount of propofol was also present in his system.

The medical examiner's official findings are expected to be presented sometime next week.
