Bleach may have contributed to the death of Archie Dale Hall, but it was not the sole cause, a forensic pathologist told a Hamilton County Juvenile Court jury Thursday.

        “He could have had some kind of pre-existing infection. But I don't believe he did,” said Dr. Gary Utz, who performed Mr. Hall's autopsy.

        He speculated Mr. Hall vomited and ingested the fluid, which then triggered the respiratory problems that led to his death. And, he added, if there was vomiting, it was caused by Mr. Hall's exposure to bleach.

        The 39-year-old Avondale man died in February three weeks after his teen-age daughter allegedly threw bleach on him during an argument over her 17-year-old boyfriend.

        The boyfriend, Gregory Douglas, is accused of placing Mr. Hall in a headlock after he'd been doused with bleach.

        According to court testimony, Mr. Douglas was trying to stop the older man from hitting him.

        The 15-year-old girl, who is not being named because she is a juvenile, is charged with involuntary manslaughter and felonious assault. She was 14 at the time of the Jan. 28 incident.

        The girl told authorities differing versions of what happened. Her father either punched or pushed her and she fell and spilled bleach on herself.

        She said the bleach burned her eyes and face and she tossed the bottle away before running out of her room. She said she didn't know if the bleach landed on her father.

        Prosecutors believe the girl intentionally threw bleach on her father. According to testimony, she threatened to throw something at Mr. Hall if he didn't leave her alone.

        Witnesses told authorities both the girl and Mr. Hall were drenched with bleach and that both complained of breathing problems.

        Earlier trial testimony indicated that bleach alone would probably not trigger the rapid onset of breathing problems that caused Mr. Hall's lungs to stiffen and fill with fluid.

        Defense attorneys hope to prove that Mr. Hall aspirated fluid during the struggle with the boyfriend.

        They say Mr. Hall was intoxicated at the time of the incident. He was seen consuming 52 ounces of beer before arguing with his daughter, according to trial testimony.

        The trial will resume Wednesday with the start of the defensecase.
