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.

She must has been desperate, while she as a sofcore porn model during most of her career, she did has arrest for prostitution and Brandon Iron claims she shoot for Load My Mouth shorty before her death.

According to Fred Olen Ray’s Retromedia forum,Lorissa lived a pretty hard last few years in dealing with abusive boyfriends,her parents’ passings,and supposed friends taking advantage of her(and giving her more abuse),all of this according to Lorissa’s friend(and frequent director[during her early 90s B movie days])Jim Wynorski(who is also close buddies with Fred),who also says that Lorissa committed suicide due to being unable to deal with all of the stress she underwent,which is a pretty sad fate for a lady who was a major part of the 90s Scream Queen brigade.

Lorissa was one of those girls who I thought as really hot despite her breast implants. She also was one of the few porn models (yes she was softcore most of her career) that openly had a Irish heritage, I only recall Jill Kelly and Collen Brennan using her irishness as a selling point. Unlike most Italian and Latina who practically rub her ethnicity in your face.

Harvey, she shot herself, which women rarely due so things must’ve been awful.

If she shot herself presumably the “long battle with illness” was depression.

Is odd, women try to commit suicide more than men but often do with less efective means, like poison, slitting her wrists and things like that who often allow for a change of mind.
Men hang themeselves, shot themselves or jump from buildings.
But namy PW have used manly ways to commit suicide. Shauna Grant, Megan Leigh, Savannah shot themselves, Alex Jordan hanged herself and Naugthia Childs jumped.
I bet she was Bipolar or has PTSD or both since both diseases are comorbid. You can have both and many sex workers have them. That sets them for a mean chronic depression.
So I agree with Natal, RIP Lorissa.
