An attempted murder charge against convicted killer Mark Twitchell was stayed in an Edmonton courtroom Friday.

The charge was originally laid for an attack on Gilles Tetreault in 2008 -- one week before Johnny Altinger was killed.

Crown prosecutors have a year to resurrect the charge. The lawyer who represented Twitchell during his murder trial asked to be removed as counsel for the case.

On April 12 of this year, a jury found Twitchell guilty of first degree murder in the killing of Altinger.

Twitchell bludgeoned and fatally stabbed Altinger in a Mill Woods garage in October 2008. Nearly two years later, some of his remains were discovered in a sewer in a north Edmonton alley near the home of Twitchell's parents.

He was sentenced to life in prison with no chance of parole for 25 years.
