LOGAN, Ohio (AP) -- A southeast Ohio prosecutor says evidence indicates a woman found dead in a septic tank was face-to-face with her killer when she was strangled with a plastic zip tie last year.

The Hocking County prosecutor opened a trial Monday by telling jurors that the victim was strangled by her estranged husband.

Twenty-seven-year-old William Inman II and his parents are charged in the death of his 25-year-old wife, Summer. Authorities say she was abducted, strangled and dumped in an underground septic tank behind a church in nearby Athens County.

Inman and his parents have pleaded not guilty to murder charges and are being tried separately. Inman's trial is the first of the three.

His attorneys didn't make opening statements Monday but said they might do so later.
