WAIPAHU — A teenage girl who witnessed a murder-suicide involving family members early yesterday morning is in critical condition after being shot in the face.

The bodies of a woman, 34, and man, 36, were found at 12:42 a.m. in a pickup truck parked in front of 94-170 Leokane St. near the corner of Pupu'ole Street in the industrial section of Waipahu. Autopsies determined the woman died from a gunshot to the neck and the man from a self-inflicted shot to the head.

The death of the woman was homicide and the death of the man was suicide, the medical examiner's office said. It was the eighth homicide of the year. Last year by this time, there were six.

The medical examiner is not releasing the names of the woman and man until their identities are confirmed.

The girl, 14, is in critical but stable condition at The Queen's Medical Center, said Lt. William Kato, supervisor of Honolulu police homicide investigations.

Police have not questioned the girl, but the autopsy findings appear consistent with statements she made to a motorist who stopped to help her.

"A witness driving on Pupu'ole Street saw the girl, who said, 'I've been shot, help me please,' " Kato said. According to the witness, the girl said her stepfather shot her mother and her before shooting himself, Kato said.

The motorist took the girl to St. Francis-West Medical Center. The hospital notified police.

The girl was later taken to Queen's.
