The interest for a second season of Making a Murderer keeps growing as new information about Teresa Halbach's murder case is revealed. Kathleen Zeller, Steven Avery's lawyer, has previously said she's found evidence that will clear Avery who she thinks was framed for Halbach's murder as many others believe. Halbach's newly released death certificate would suggest there was in fact a rush to charge Avery without sufficient evidence. Now according to Zeller, Avery has an "airtight alibi" that will prove he's innocent. 

The death certificate is riddled with contradictory information. One of the troubling things in the certificate is how authorities identified Halbach's remains on December 5, 2005 though the remains were not officially confirmed until a little over a month later. 

Zeller who's been tweeting about the case told TheLipTv last month Avery was wrongfully convicted:  

"It's the evidence. In having had a number of these cases, it has the signature of a wrongful conviction case. They only focused on him. They did not look at a lot of other suspects, certainly some very key people they should have been looking at. There was a very poor investigation done of the victim's background, who she was involved with, the circumstances of her life. It had all of the hallmarks of a wrongful conviction case."

Yesterday Zellner tweeted about the new information in the case:

As Uproxx reports, Zellner has obtained Avery and Halbach's cellphone location data from cellphone towers. Uproxx points out Halbach's cellphone records (including both incoming and outgoing calls) were discussed in the original trial, but not location data.

Location data could reveal where Halbach was last in the hours before her disappearance. Halbach was last at Avery's Salvage Yard, according to the prosecution, but some people think she may have gone somewhere else after that.

Uproxx points out the location data isn't much of an alibi for Avery because he very well could've left his cellphone at the salvage yard while moving Halbach’s body to another place.

More information is bound to come up, so for now, here's another possible puzzle piece.
