CHICAGO (AP) - The start of testimony in Drew Peterson's murder trial comes in the wake of public acrimony between the former Chicago police officer and relatives of his former wives.
Attorneys deliver opening statements Tuesday. Jurors will decide if the 58-year-old killed his third wife, Kathleen Savio. He's also suspected in the disappearance of his fourth wife, Stacy Peterson.
Many Savio family members are potential witnesses, so can't speak publicly.
An outspoken member of Stacy Peterson's family, younger sister Cassandra Cales, tells The Associated Press she can barely sleep because she's so anxious about the trial.
After Drew Peterson's 2009 arrest, Cales told reporters it was good to see him chained up, in her words, "like the dog that he is." Peterson has tried to paint the Stacy Peterson family as troubled.
