Moammar Gadhafi was killed by a shot to the head according to Libya's chief forensic pathologist

TRIPOLI, Libya (AP) -- Libya's chief forensic pathologist says an autopsy has confirmed that Moammar Gadhafi was killed by a shot to the head.

Dr. Othman al-Zintani says doctors completed the examination on Sunday but he won't disclose more details until he delivers a report to the attorney general.

Bloody images of Gadhafi being taunted and beaten by his captors in his hometown of Sirte have raised questions about whether he was killed in crossfire as suggested by the government or deliberately executed.

International concern about the issue has clouded plans by the transitional government to declare liberation later Sunday after months of bloodshed amid a rebellion to oust the hated leader of nearly 42 years.
