Charlie Sheen's legal woes continue to mount up - he's now being linked to the death of a porn star. CHLOE JONES, a former Penthouse Pet, was found dead in her Houston, Texas, home last June (05) - just months after going public with a steamy affair she had with Sheen. And now the X-rated star's mother DONNA is considering filing a wrongful death suit against the actor because she thinks he drove her daughter to take her own life. Speaking exclusively to American tabloid the Globe, Donna Jones says, "I've seen a lawyer about filing a wrongful death suit against Mr Sheen. I think he didn't slip her the pills - but he drove her to it with death threats. "She'd (Chloe) call me 10 times a day telling me of her fears. She was terrified to death of the guy." And the actor's estranged wife Denise Richards has her doubts too - in explosive legal papers filed last month (APR06), the former Bond girl admits she confronted Sheen about Jones' death when she learned the mother-of-three had died from liver failure after taking an accidental overdose of prescription drugs. In the documents, Richards reveals, "I saw on the news that she had died from undetermined causes. When I asked him if he had anything to do with her death, he said he had 'no comment'... This scared me." Richards has since won a temporary restraining order against Sheen after claiming the actor made threats on her life if she went ahead with plans to expose his alleged obsessions with internet porn and gambling throughout their three-year marriage.
