Kidnapped two guys and held them for ransom. One hostage was set free weeks later while the other wasn't so lucky. The body was eventually found in a basement cemented buried in the ground.
Cops busted into the flat (I rented a room in an apartment - he lived in it before I moved in) and apprehended my roommate while he was sleeping. Tried for kidnapping and manslaughter along with his other few associates.
This was in Ontario, Canada around 2011/2012. I never really followed the story after I moved the hell out and learned that they were all in jail.
My roommate was Sohaib Malik. He seemed like a normal, nice dude. Student at the local university. Had no problems with him (aside from him using my kitchen knife without permission).
