Supporters of Steven Avery have grown in number following the release of the Netflix documentary "Making a Murderer" earlier this month, Business Insider reported.

Viewers of the documentary, which chronicles Avery's streak of bad luck with the Manitowoc County, Wis., Sheriff's Office, have complained about certain aspects of the investigation and trial.

However, Manitowoc County Sheriff Robert Hermann says that the documentary's portrayal of the Teresa Halbach murder trial is unfair.

"I won't call it a documentary, because a documentary puts things in chronological order and tells the story as it is ... I've heard things is skewed," Hermann said in an interview with htrnews.com.

The documentary has also launched online petitions encouraging President Barack Obama to pardon Avery and his nephew Brendan Dassey, who was also convicted.

One petition asks Obama "to encourage the judiciary to re-examine the trials of Steven Avery and Brendan Dassey," while another urges Obama to "pardon the Averys in Wisconsin and punish the corrupt officials who railroaded these innocent men."

These petitions were attached with a short note. "Watch 'Making a Murderer' on Netflix. It tells the entire story," the note reads, according to Entertainment Weekly.

Avery was sent to prison for allegedly raping and attempting to murder a jogger and served an 18-year sentence. He then filed a $36 million civil suit against the officers responsible for putting him into jail.

However, he was arrested again, by the same officers whom he filed the civil suit against, for allegedly murdering photographer Halbach back in 2005, according to zap2it.
