Lorissa was a well known model and Playboy model throughout the 90′s. Her Wikipedia page says Lorissa was a nude and softcore model. But she has an IAFD page where she has a few girl/girl credits. Most of her credits there are non-sex roles. Her official website Lorissa.com doesn’t say anything about porn. So I don’t know if she did full fledged porn or was just softcore.
They don’t say what her illness was. Her website has released this statement:
On November 3rd, 2009, after a long battle with illness, Lorissa McComas passed away. Lorissa’s family is going through the grieving process and will release more soon on this web site . Lorissa leaves an extensive body of work from photographs to video. She is fondly remembered by family, friends and her fans, whom she deeply appreciated and considered her friends.
