With his dramatic first-degree murder trial ending with a conviction, Mark Twitchell faces the possibility of additional charges.
Twitchell was convicted Tuesday in the death of John Brian Altinger and was sentenced to life in prison with no chance of parole for 25 years.
He still faces a charge of attempted murder for an alleged attack on Gilles Tetreault, who also testified during the four-week murder trial.
Alberta Justice spokesperson David Dear said a decision has yet to be made about whether the Crown intends to pursue the attempted murder charge.
"The Crown is still in the process of making a decision on that," he said.
Even though the Crown cannot extend Twitchell's life sentence with another conviction, there are other reasons to consider pursuing it, he added.
"A Crown might look at a case and say that if they pursued a second conviction it might ultimately affect the person's ability to obtain parole."
Twitchell also has 30 days to appeal his first-degree murder conviction.
New information
Despite the huge volume of evidence presented in the Altinger case, there were details the jury did not hear.
Due in large part to its inflammatory nature, some of the evidence was held back from the jury and was covered by a publication ban that ended when deliberations began.
Among the evidence not presented were several parts excised from SKconfessions. The document, which the Crown contended was a diary, details Twitchell's life around the time of the murder and includes graphic details about the dismemberment of Altinger's remains.
In one passage that was blacked out, the killer character is giddy at the prospect of dismembering a body and makes light of the heinous act.
"I may as well enjoy the fun part," it reads.
In both the diary and another document that was withheld in its entirety, Twitchell references coming to the conclusion he is a psychopath.
"I had found out through introspection and discussions with therapists that I am in fact a psychopath in almost every clinically defined sense."
The jury also did not see a long document prepared by the Edmonton Police Service, which they presented to a judge to obtain search warrants for Twitchell's home and the garage he rented in south Edmonton.
Though most of that evidence was presented to the jury, they did not hear that Twitchell was interested in purchasing a firearm.
According to the document, when police interviewed one of Twitchell's friends Joss Hnatiuk, he told them Twitchell had asked him to be a reference so he could obtain a gun licence. Hnatiuk also indicated he received a phone call from the RCMP checking on the reference.
