The Oakland, Calif., woman who stopped in the middle of the street, gave birth and then walked away was released from jail -- after laughing about the matter with police. The baby was four months premature and stillborn, so police say they had no choice but to release her.

Alisyn got it right in the comments in the initial post -- drugs are definitely a factor. Turns out the 25-year-old is a homeless prostitute crackhead, er, drug user, who told police the baby came from one customer or another.

From what she told police ...

"She was pretty much nonchalant," homicide Sgt. James Morris said. "She wasn't sorry she got caught and she didn't seem concerned about what happened. She thought it was funny." 

... I just hope she was high throughout the whole ordeal -- high as a freaking kite. There's no other explanation for such callousness craziness.
