Making a Murderer lawyer claims Steven Avery has 'airtight alibi' in murder case

'Cellphone tower records of (Avery and Halbach) provide airtight alibi for him. She left property he didn’t'

Steven Avery, the subject of the new Netflix documentary

Since the release of Making a Murderer, the curious murder of Teresa Halbach has been brought into the limelight once more, with convicted murderer Steven Avery at the centre of it all.

In December, Netflix released the 10-part series, in the process creating hundreds of armchair detectives, all attempting to answer the question; did Avery really murder Halbach in 2005?

In recent weeks, his new lawyer, Kathleen Zellner, has vowed to prove her client's innocence, saying she has found forensic evidence that will help her case.

Now, she claims Avery has an “airtight alibi” that will prove had nothing to do with her murder. Writing on Twitter, she explained: “Cellphone tower records of (Avery and Halbach) provide airtight alibi for him. She left property he didn’t.”

Zellner claims there are phone call records that were never heard during the original hearing, and that they prove the pair were not together at the time of her murder.

She previously said that it was “obvious” who did actually commit the crime, but failed to detail who.

Since the series’ release, many members of the original prosecution and defence have become celebrities in their own right. Dean Strang and Jerry Buting, Avery’s defence team, are going on tour together, with Buting publishing a book on the American justice system.

Meanwhile, Ken Kratz has spoken out against the series, saying the filmmakers made him seem like a ‘supervillain’ while also revealing what he claimed to be evidence left out of the docudrama.
