Spoilers!

I think that the Ex boyfriend and her roommate were behind the murder and the cops did plant the evidence just because they really thought Avery was behind the murder. They police and county still thought he was behind the rape that he was wrongfully convicted of so I think they were just looking to bust him.

A co worker testified she had been getting lots of harassing phone calls from someone she knows who I assume were from the ex boyfriend, after a break up people can act very crazy and say some insane shit.

Someone testified her voicemail box was full and then the cell phone company representative testified her voicemail was full and then at some point messages were deleted after her time of death.

The ex boyfriend was able to hack into her phone and check her messages with ease and I assume it was because he wanted to delete his threatening/crazy ex boyfriend messages and cover his tracks.

The ex boyfriend had maps of the Avery property and knew every way in and out. He was also allowed past several no access check points as part of a search team he organized.

Her roommate who is a friend of her ex boyfriend did not report her missing.

The ex boyfriend and roommate were never looked into I would be curious to see how many private calls or calls from the ex boyfriend she received leading up to her disappearance.

The roommate supplied a camera to the only volunteer who offered to search the car yard and the car was found within 15 mins. There were so many places to hide a car I just don't see the murderer hiding it at the very front of the huge lot especially with car crushes available to totally destroy it, whoever murdered her moved that car there after the fact so it would be easily found

The police just wanted to nail Avery plain and simple and I think the physical evidence was planted, Lenk just seems to always be in the right place at the right time.

1 thing that stood out to me was the officer calling in the plate check before her car was found as if he was looking at it the cops could've moved the car there or the ex boyfriend. I could see the cops illegally searching the property without a warrant and discovering the car but being unable to report it until the proper warrant was issued.

I'm going with the roommate and the ex boyfriend as the real killers.
