The Los Angeles Coroner's chief investigator re-visited the office of Michael Jackson's dermatologist Wednesday even though the coroner announced last week his "thorough and comprehensive" report was completed.
"We wanted some additional information and they provided it," Ed Winter said as he emerged 90 minutes after entering Dr. Arnold Klein's Beverly Hills, California, dermatology clinic.
Winter, who also visited Klein's office on July 14, said the doctor's staff and lawyers cooperated with his requests.
Garo Ghazarian - one of Klein's two lawyers on the scene - said the doctor did not meet with Winter.
"They had inquiries born out of information they wanted to corroborate," Ghazarian said.
Ghazarian said he was added to Klein's legal team "to take a look and see if there's any cause for concern in light of media reports" that investigators were considering criminal charges against him.
"I have seen no cause for concern on behalf of my client, Dr. Arnold Klein," Ghazarian said.
The coroner's office said more than a week ago that a "thorough and comprehensive" report into the death of Michael Jackson is complete, but police have requested that the report not yet be released because of the ongoing criminal investigation.
The coroner's office said it would abide by the request that "the cause and manner of death remain confidential," and referred all questions to the Los Angeles Police Department.
Winter would not say what prompted the coroner's office to re-visit its conclusions.
Jackson's June 25 death is also the focus of an investigation by Los Angeles police, the state attorney general's office and the U.S. Drug Enforcement Administration.
Klein, who treated Jackson for decades, denied in a CNN interview last month that he had given Jackson dangerous drugs.
"If you took all the pills I gave him in the last year at once, it wouldn't do anything to you," he told CNN's Larry King.
Jackson visited Klein's office several times in the weeks before his death, including one visit just three days before.
