Kathleen Zellner is asking for more time before taking the next step in her efforts to win Steven Avery's freedom.

Zellner, who along with attorneys Douglas Johnson and Tricia Bushnell, are working in hopes of exonerating the convicted killer and "Making a Murderer" centerpiece, filed a motion this week to extend the deadline on her defendant-appellant's brief by 90 days.

The requested deadline is Aug. 29. The motion was submitted to the Wisconsin Court of Appeals on Wednesday.

The reason for the request, according to court documents, is the current workload on the trio of attorneys.

Zellner has been working on Avery's case since January. And although she is yet to file the appeal, she's been quite vocal on Twitter about her findings since getting involved. She's tweeted that cellphone records indicate Avery has "an airtight alibi" for Teresa Halbach's murder. She also has said police turned a "blind eye" to those who lied during the investigation, planted evidence, had "tunnel vision" by focusing on Avery as the only suspect and relied on "poorly done" forensic testing.

Odds and ends

► USA TODAY NETWORK-Wisconsin investigative reporter John Ferak published a story Thursday looking at the key evidence collected by the Manitowoc County Sheriff's Department despite potential conflict of interest issues tied to Avery's $36 million civil rights lawsuit.

The Manitowoc County Sheriff's Office could have avoided worldwide scrutiny in the wake of the "Making a Murderer" series if it had just stayed away from the Avery Salvage Yard in November 2005, Ferak writes.

► The Dean Strang-Jerry Buting road show, dubbed "A Conversation on Justice," rolls on with speaking dates in Minneapolis on June 2 and Chicago June 3. In advance of the Chicago event, Buting spoke to The Chicago Reader about the tour, their famous case and — as always — life as an internet heartthrob.

One highlight of the interview: Buting calls the post-"Making a Murderer" campaign by Ken Kratz, which included claims that the docu-series left out key evidence on the side of the prosecution, "sour grapes."

► Bustle.com published a list titled "8 regular people fighting for Steven Avery and Brendan Dassey's freedom," which gives a few shout-outs to "Making a Murderer" viewers who are doing what they can to right what they see as injustice. One man is said to be hunting Halbach's "real killer." Another created petitions that gathered more than 500,000 signatures. Another regular person who is fighting for Steven Avery and Brendan Dassey's freedom, Twitter user @VioletSkyye, "tweeted a clever point."
