Charles Petty, adviser on review of JFK slaying

DALLAS -- Dr. Charles Petty, a medical adviser to a US House committee that reviewed the circumstances around President Kennedy's assassination, died Tuesday. He was 86.

Dr. Petty died in Dallas County, according to the medical examiner's office that he opened in 1969.

Dr. Petty, a native of Seattle , was not in Dallas when Kennedy was shot in 1963, but he worked with the House of Representatives Select Committee on Assassinations in the late 1970s to review the findings.

In a 2003 appearance on CNN's "Larry King Live," Dr. Petty said he concluded from his work with the House investigation that Kennedy was struck by two bullets.

Dr. Petty wrote in a 1993 article in the Journal of the American Medical Association that the assassination carried important lessons, among them that pathologists must have control of the time and place of autopsies , The Dallas Morning News reported.

He told CNN in 2003 that he believed that the doctors who worked on Kennedy at Parkland Memorial Hospital should have been taken to Bethesda, Md., where the autopsy was performed. But he said the autopsy was done well.

Dr. Petty was Dallas County medical examiner from 1969 until his retirement in 1991. When the office opened, Dr. Petty had a secretary, a typist, and a forensic scientist working with him. He built the agency into a fully integrated medical and criminal investigative system within five months, according to the newspaper.
