Closing arguments could begin Thursday in the trial of a homeless woman accused of setting a deadly fire in Wrigleyville. In March of last year, investigators say Mary Smith broke into the front door of the three-story apartment building and lit a dollar bill to stay warm. That fire quickly spread through the building and killed four friends who were asleep at the time.

Testimony is expected to wrap up Thursday, paving the way for closing arguments.

Smith's defense claims she was insane.
