An Edmonton jury got a close look Friday at the tools police believe aspiring filmmaker Mark Twitchell used to kill and dismember John Altinger.

The Crown entered as evidence a portable butchering set with more than a dozen tools including a meat cleaver, knives and saw. Jurors also saw a 60-centimetre pipe with black tape wrapped around one end that police believe to be the murder weapon.

All the instruments were found stained with blood in a garage Twitchell was renting, said Const. Nancy Allen.

Twitchell is a charged with first-degree murder in the death and disappearance of Altinger in October 2008.

Earlier in the day police continued to reveal how they meticulously built the case against Twitchell.

Allen told the jury how investigators went through Twitchell's garbage can and painstakingly reassembled shredded notes.

One message read "Get disposable raingear," another, "For Friday get new lock hardware."

Police believe Twitchell, 31, tried to kill a man on Friday Oct. 3, 2008 and that he did kill Altinger on Friday, Oct. 10, 2008.

Police suggest Twitchell lured Altinger through an internet dating service to the garage in the Mill Woods area of Edmonton.

The jury also saw blueprints that had been seized from Twitchell's home office in St. Albert, Alta.

One drawing showed a table and two chairs — one chair is labelled "victim chair," the other "killer chair."

The Crown believes Twitchell beat Altinger with a pipe, stabbed and dismembered him before tossing his remains down a sewer.

The trial began Wednesday at Court of Queen's Bench in Edmonton and is scheduled to run six more weeks.
