I found this article that gives a detailed account of the events leading up to the disappearance of Toni Sharpless, a 29-year-old nurse who went missing just over a year ago. Toni was bipolar, but very high-functioning — none of her friends even knew she had the condition. Unfortunately right before she disappeared, she was drinking heavily and she had been up for 36 hours straight. That’s not good for anyone but it’s especially bad for someone with a mental illness. And the article says she wasn’t taking her meds regularly. This probably contributed to her disappearance.
The private detective Toni’s family hired to investigate her disappearance has talked to me. The detective’s theory is that she is alive and was forced into prostitution. I’m wondering though, since her car was never found, if she isn’t in a lake somewhere. Drunk and upset, she may well have accidentally driven off the road.
One thing I’m sure of is that she didn’t leave on her own. Toni is described as a devoted mother to her young daughter, whom she was bringing up alone, and her job shows that she was a responsible person.
