Jurors in the Steven Avery trial will go back to work this morning. They deliberated for four and one-half hours Thursday, before wrapping things up around 5:30 p.m.

Seven men and five women are poring over testimony from 60 witnesses and almost 500 pieces of physical evidence.

It's all related to the Halloween 2005 killing of Teresa Halbach at the Avery family's auto salvage yard near Mishicot.

In his closing argument Thursday, Dean Strang, defense attorney, told the jury to "set things right," after another jury wrongfully convicted Avery in a 1985 sex attack.

Strang also hammered home the defense's claim that investigators planted evidence in order to prove Avery guilty.

But Ken Kratz, prosecutor, told jurors if they believe the defense theory, they must also believe the police were the ones to kill Halbach.
