Gov. Scott Walker will not issue a pardon to convicted killer Steven Avery, a spokeswoman for the governor said Tuesday.

Walker's press secretary Laurel Patrick noted that early in his administration Walker decided he would not issue any pardons.

"Those who feel they have been wrongly convicted can seek to have their convictions overturned by a higher court," Patrick said in a statement.

Avery, 53, was convicted of killing 25-year-old photographer Teresa Halbach in 2005 in Manitowoc County and sentenced to life in prison.

The statement from Walker's office came against the background of the Netflix documentary series "Making a Murderer" that has renewed the debate over Avery's guilt.
