Back in 2006 a male porn star named Timothy Boham murdered a guy in Denver. Boham is serving life for that crime. Rumour has it that Luka knew Tim and may have been roommates. In this news story HERE about the murder, Luka responds a mere 7 months ago in Jan. 2012 and posts confirmation of his close relationship with Timothy Boham the gay porn star convicted murderer.

There is more, 
back on March 2, 2008 Luka responded HERE to defend Tim Boham being charged with the murder with these quotes: 

"I am a male porn star too. I would expect (like everyone else) if I were on trial to have a FAIR trial. The MEDIA is making him out to look like a bad guy"

"He seems to me like he should be found NOT guilty due to emotional and mental issues"

On this other random posting I threw in, Luka mentions that he is an Atheist - "Luka is on an S&M forum while in Russia Nov. 2010" also a screen shot is HERE.
