Sarah Widmer suffered bouts of sleepiness, migraines and blurry vision in the months before her she drowned in her Hamilton Township bathtub, witnesses say. They also testified she suffered from a headache and stomachache hours before her death.

The testimony Thursday in the retrial of her husband, Ryan, was intended to support defense lawyers’ contention that Sarah, 24, may have suffered from an undiagnosed condition that contributed to her drowning in August 2008. Prosecutors allege the drowning was murder, and Widmer faces 15 years to life in prison if convicted. The trial enters its 10th day Friday and could last all next week.
