The investigation came about after several explosions took place in two neighborhoods where Mork lived.

So explosives had already been detonated before he was arrested?

In addition, investigators found disturbing material on his computer, including "violent child pornography," "snuff films," and images of the suspect having sexual relations with "seemingly unconscious women," according to the Review-Journal.

What in the fuck?

Mork has yet to be charged with crimes relating to the content on the computer. "They're still trying to image that drive," prosecutor Jake Villani told the Review-Journal. "This was just a triage approach to that drive.

So it seems he hasn't even been charged for any of the materials found on his computer, they're going off of the explosives thus far.

Mork's mother told the Review-Journal from Minnesota that she noticed some peculiar behavior from her son when he visited his parents two years ago. He had been taking medication for depression.

It's also worth noting that in the news video provided in the link from OP, the suspects' mother also says that he was also on adderrall, but didn't mention any medications pertaining to depression. Wasn't James Holmes (Aurora Theater Massacre) also on anti depressants?
