I would expect a lawsuit against VH1 is inevitable after the alleged murder by one of their reality-show contestants. TMZ.com reports:

Producers of the reality show on which accused murderer Ryan Jenkins appeared admits it didn’t do a “full” background check. What’s not clear … did it do any background check at all?
51 Minds — the company that produces “Megan Wants a Millionaire” — admits it was not aware that Jenkins had been convicted of assaulting a girlfriend when he was cast on the show. This is always a problem when you have someone with violent propensities sharing a house with unsuspecting strangers.
A company rep tells TMZ, “Obviously, if the company had been given a full picture of his background, he would never have been allowed on the show.”
