11:25 a.m. Prosecution ends closing argument 

Prosecutor Chris Koch ended his 70-minute argument.

“Taking all of that information together and drawing reasonable inference from them... we have proved to you beyond a reasonable doubt that he entered that home with the intent to kill her, that he forced her down, that he held her under water to cause her to drown, and she died, and because of that, ladies and gentleman, we are asking you to find him guilty.”

Following Koch's argument, Judge Edward Burmila gave a brief break to the jury.

11:20 a.m. Closing shifts to Stacy Peterson

The medical evidence about Kathleen Savio’s injuries, her statements about Drew Peterson's threats, and Peterson’s own statements to police and others about her death and his monetary gain, all point to the fact that “he went into that house, and forcibly held her down so that she could inhale fluid so that she could drown.”

With that, Koch turned his focus to Stacy Peterson and her statements to her pastor, Neil Schori.

“She said that she had something to talk about regarding the evening that Kathy died,” Koch said.

“Stacy woke to find her husband missing, and could not reach him by phone, only to later find him placing his clothes and clothes from a bag in the washing machine,” Koch said. “They were women's clothes, and they weren't hers.

“The defendant said soon the police would be wanting to sit down and interview her, and he told her what to say to the police.
