It's been a week of outrage, disbelief and small graces for victims of crime in Alberta.

Watchers at an Edmonton court room expressed their anger audibly on Friday, after hearing that all charges were being dropped against a teen charged in the violent murders of two city residents.

It was alleged the teen boy killed Barry Boenke, 68, and his friend Susan Trudel, 50, after escaping from a youth home.

The Crown said it no longer had a case after the judge dismissed all evidence gathered by the RCMP under a Mr. Big sting.

Earlier in the week, authorities and commentators were left in disbelief when they learned that Mark Twitchell, who came to be known as the Dexter Killer after admitting the TV show inspired him to murder a man and to attempt to kill a second, had his own flat screen TV in his cell and on which he watched as much Dexter as he desired.

Twitchell is serving a life sentence for luring a man to his rented Edmonton garage, killing him, dismembering him and disposing of the remains in the city's sewer.

And it was a small solace but a solace nonetheless after three teens were sentenced on Friday to the max for killing Ethan Yellowbird, while the young boy slept in the Samson Cree reserve.

The three took turns firing a rifle into the central Alberta home of a Native chief. One of the bullets hit the five-year-old while he was sleeping, killing him instantly.

The culprits all being teens, their sentences will count more in the months than in the years.

But although it was one particularly busy week in Alberta courts, that is not to say violence and grisly crime is worse now than before.

In fact, as the gallery below - which highlights some of the most notorious crimes in Alberta history - shows, crime has and will likely always be present as long as human beings are part of the equation.

    Only days after the infamous Columbine school shootings in April 1999, a southern Alberta teen saw a way to get back at his own tormenters and unleashed a hail of bullets inside W. R. Myers High School in Taber. The rampage ended with one 17-year-old dead, a second one wounded, and the 14-year-old drop-out behind the trigger being subdued by an unarmed school police resource officer. The shooter was described as unpopular and the victim of teasing and name-calling. By contrast, the fatally wounded student, Jason Lang, was a popular student and the son of a preacher. The second teen made a full recovery and the shooter pleaded guilty to <a href="http://www.cbc.ca/news/background/taber/" target="_hplink">all charges, including murder</a>.
