Several pieces of evidence were not allowed into trial, which Hogue's pro-bono attorney Andrew Casey believes could have helped her case.
The tree-carving with the words "Rebecca is innocent" was considered hearsay, and a ban was placed on distributing those images.
The lead detective who investigated the murder was not allowed to give his opinion on the merits of the case, and an audio recording that captured him discussing it with a friend of Hogue was not allowed into court.
On the recording, obtained by the BBC, he admits that his team looked into the question of whether to lay charges and decided they did not have enough evidence for a "failure to protect" first-degree murder charge.
"We don't believe in this charge and there's a good chance she ends up in prison anyway because of the way the system is," Detective Sean Judy can be heard saying on the recording.
The district attorney's office chose to bypass police charges by asking a jury to ask a jury to decide if charges should be brought, which is allowed in some American jurisdictions, rather than bringing police charges. Ultimately, the jury decided charges were warranted.
The district attorney did not respond to the BBC's request for comment.
And finally, the jury were not allowed to hear expert testimony about Hogue's previous experiences with domestic violence and how it could affect her, because she was not the one being physically abused by Trent.
Over the eight-day trial, prosecutors repeatedly showed graphic images of Ryder's dead body covered in bruises, including leaving a picture of his bruised genitals up for 10 minutes during closing arguments.
It took the jury less than two hours to convict.
