Lawyer for ‘Making A Murderer’ subject Steven Avery says he has an ‘airtight alibi’

Avery is currently serving a life sentence for the murder of Teresa Halbach

The lawyer for Making A Murderer subject Steven Avery has said his client has an “airtight alibi”.

Avery, 53, is currently serving a life sentence for the murder of Teresa Halbach. Her remains were found near Avery’s house and prosecutors claim she was last seen near his salvage yard.

Lawyer Katherine Zellner has now reportedly filed a new appeal for her client and has been tweeting her thoughts on the case.

“Cellphone tower records of SA & TH provide airtight alibi for him. She left property he didn’t,” she wrote in one.

As BBC reports, Zellner claims only incoming and outgoing phone calls were discussed in trial, but more detailed information is now available.

Avery is the subject of Netflix series Making A Murderer. Reports have emerged suggesting that a second season of ‘Making A Murderer’ is set to be recorded, and that it will reveal “explosive new evidence.”

Since the Netflix series – based on a dubious-looking murder conviction – took off, subject Stephen Avery’s case has gained a host of publicity, with the man himself writing from his jail cell to protest his innocence, and prosecution lawyer Ken Kratz promising a tell-all book in which he says he’ll prove Avery’s guilt.
