CHICAGO (MCT) — Assuming the Drew Peterson prosecution rests Monday and the judge does not dismiss the murder charge — two highly likely, but not guaranteed, scenarios — the former Bolingbrook, Ill., police sergeant’s attorneys will launch a defense.

Over the next few days, they are expected to call pathologists and law-enforcement officials to help bolster their assertion that Peterson’s third wife, Kathleen Savio, died after accidentally falling in her bathtub and drowning in 2004. Prosecutors contend that he killed her amid a bitter divorce in which they battled over his pension and child-support payments.
