Charla Nash, the Connecticut woman who was severely mauled by a friend's pet chimpanzee, remains under sedation, according to her doctors at the Cleveland Clinic in Ohio. The Stamford Advocate reports that they revealed the extent of her injuries as well: Nash, 55, "lost her nose, lips, eyelids, hands and bone structure in her mid-face and suffered significant brain, eye and tissue injuries in the attack." The hospital said that while her injuries have stabilized, "critical issues still remain related to a significant traumatic brain injury and injuries to her eyes that threaten her vision." The Stamford, CT police say the toxicology results for 200-pound chimp Travis, who was shot dead after the attack, will be available in the next few days. The decision whether the police will charge Travis's owner, Sondra Herold, (the police's criminal investigation is continuing) will take weeks. Nash's brother Stephen told the AP, "She's tougn. I'm optimistic. I think she can do it."
