UPDATE: Kathleen Zellner has arrived at the Manitowoc County Courthouse to file court documents asking for post-conviction testing of evidence in the Steven Avery appeal.

Zellner believes this testing will prove Avery's innocence. Most of these tests that she has selected were not even available during Avery's original trial.

Zellner says the tests will set Avery free and also implicate someone else in the death of Teresa Halbach, although she has not state who that person is.

Evidence noted in the motion include Teresa's car key, blood on the car, a pair of underwear found at the scene and a bullet.
