Ex-policeman Drew Peterson\'s request for a new trial in the death of his third wife began Tuesday in Joliet, Ill., with a claim his lawyer botched his case. Peterson is arguing he deserves a new trial because his former lawyer, Joel Brodsky, mishandled his defense against charges he drowned Kathleen Savio in 2004, the Chicago Sun-Times reported. Attorneys will also argue over dismissal of a wrongful death suit filed by Savio\'s family, but in Tuesday\'s hearing, Peterson\'s new legal team underscored their claim of Brodsky\'s mishandling of the case by putting Reem Odeh, a former law partner of Brodsky\'s on the stand. Odeh said Brodsky talked with her, on \"many occasions.\" about potential money their firm could make with Peterson as a client, and testified Brodsky physically attacked her to stop her from taking a copy of an agreement with a publicist, after the law firm split up. Brodsky denied each of her accusations. Law professor Clifford Scott-Rudnick was then called to the stand, who said Brodsky violated ethical standards by signing a contact with a publicist and, in essence, becoming Peterson\'s business partner, an action Scott-Rudnick called \"over the line.\" Prosecutors contend Peterson received a fair trial and say alleged violations of professional responsibility by Brodsky do not indicate Peterson had ineffective counsel, the newspaper said. If Judge Edward Burmila denies Peterson\'s motion for a new trial, a sentencing hearing could begin. Peterson faces up to 60 years in prison.
