Before she was kidnapped and before she was killed and her body burned in a chicken house in Newton County, Olamide Adeyooye was simply a student. And like many people her age, she had a weblog, an online journal that people all over the world could access, full of personal information like where she lived, where she went to school and where she worked.

Police in Illinois now consider her blog evidence. They say whoever killed her might have used it to access that personal information.

It highlights a trend that might be dangerous, having too many people know too much information about someone.

"You want to limit what you're going to say, especially private information," said Justin Clark of MyDesktopHelp.com.

Olamide had not left anything as private as a social security number or a bank account number, but by reading her blog, you could know an awful lot about her. Her likes and dislikes, her daily routine, where she lived. They were all there, and Clark says you might want to think twice before putting anything like that on your own blog.

"It's really a personal decision, what are you comfortable with somebody knowing, and can that information be used to take advantage of you," said Clark.

Despite the dangers, some good has come out of Olamide's blog. In the comments section, hundreds of people have left condolences.

One says, "You were an angel among us."

Another says, "I know you're in heaven right now."

It's almost like an online wake, seemingly appropriate for the self-described science geek. Whether or not her blog helped cut her life short or not, it now is helping her memory live.
