Steven Avery was visited at the Waupun Correctional Institution by his Chicagoland attorney, Kathleen Zellner Friday.

During Zellner’s now fifth meeting with Avery, Zellner collected new DNA evidence that the appellate attorney says will be game-changing to her client’s appeal, according to Twitter.

“Collected samples for new tests. The inevitable is coming–he was smiling so were we,” Zellner tweeted.

As of Monday at 8 p.m., the tweet had 892 retweets and dozens of responses — while most replies were favorable, some raised questions.

“Does anyone ever stop to think about what will happen to Avery if he’s released? At this point is he safer in prison?,” a Canadian woman tweeted in reply.

Last month Action 2 News was on the scene in Waupun, during one of Zellner’s meetings with Avery.

It was then when Zellner foreshadowed some of her case strategy.

“Since 2007 there have been significant advances in forensic testing and so clearly we’re going, the clearest way to do this is with scientific testing and that’s what we will be asking to do,” Zellner said.

In 2007, Avery and his nephew Brendan Dassey were convicted of killing Halbach and were both given life sentences, which has received international attention in the wake of the release of the Netflix series, “Making a Murderer.”

During an exclusive phone interview Monday with Action 2 News, Ken Kratz the special prosecutor on the Avery trial, reacted.

“I’m not on twitter. I don’t litigate my cases over social media,” Kratz said.

“The general public is waiting for the big bombshell she’s [Zellner’s] waiting to unveil, and we haven’t seen anything yet,” Kratz added.

According to court records obtained by Action 2 News, on Feb. 10 Manitowoc County’s Clerk of Circuit Court asked for more time to gather documents related to Steven Avery’s case, as he seeks a new trial.

On Feb. 16, the Wisconsin Court of Appeals granted Manitowoc County’s request, and the county now has until March 2, to comply.
