The White House has said it cannot pardon Making a Murderer subjects Steven Avery and his nephew Brendan Dassey for their role in the 2005 murder of photographer Teresa Halbach after more than 100,000 people signed a petition demanding their release.

A petition on the government’s We The People website called for the Obama administration to free Avery after the 10-part Netflix documentary series highlighted what it was said were serious flaws in the judicial process.

The Making a Murderer series scrutinised the details of the case and the claim by Avery's defence team that some of the evidence against him had been planted by the Manitowoc County sheriff’s department in Wisconsin.

Petitions that reach over 100,000 signatures on the US government's website automatically receive an answer, but in its official response to the 129,886 signatures the White House said it was unable to intervene as it was only able to grant pardons for offences committed “against the United States” as a whole and Avery’s conviction was decided at state level.

The Governor of Wisconsin, Scott Walker, previously said he has not watched the programme and will not pardon Avery, saying he should use the court system to appeal.
