SPOILER ALERT (for the two of you at the back who've yet to watch the documentary series).

Kathleen Zellner - the top 'wrongful conviction' lawyer, who took on Avery's case after Netflix first started streaming Making a Murderer - has been very vocal on twitter regarding her client's innocence. Now she says she has an airtight alibi for the Manitowoc native. 

This is obviously in reference to Teresa Halbach’s mobile phone records, which were dubious at the time if the trail, with certain messages being deleted after her death...

A few days prior to this, Zellner tweeted...

According to Uproxx: "The prosecution has claimed that the Avery Salvage Yard was [Halbach's] last known location. Internet sleuths following the case have speculated that she may have actually visited another Auto Trader client after the salvage yard. Cellphone tower records could reveal that, and maybe even where she died... this murder went down in 2005, long before it became general knowledge that cellphones were basically tracking devices we keep in our pockets."
