Two major points emerged from testimony in the Ryan Widmer murder retrial Thursday.

An expert in sleep, epilepsy and neurology testified in Warren County Common Pleas Court that it was possible, but very unlikely, that Widmer's wife, Sarah, suffered a first-time seizure before drowning in her Hamilton Township bathtub in 2008.

And in an unexpected turn of events, defense lawyers revealed there are two versions of a medical record documenting Sarah Widmer's condition and the life-saving efforts performed on her, raising unanswered questions as to why, when and how the record was altered.

Her husband of about four months, Ryan, 29, is accused of murdering her by drowning her in the couple's bathtub. His 2009 conviction was thrown out because of jury misconduct.

Hamilton Township medics gave highly detailed, blow-by-blow descriptions of the procedures they performed on Sarah Widmer.
