A little over a year ago, Barbara Sheehan was a wife of 24 years, a mother of two and working as a school secretary. Today, the 48-year-old is up against murder charges and is months away from facing a jury that will decide her fate.

When Barbara married Raymond, a police officer, she looked forward to sharing a long and happy life with him. "We had the same beliefs and we wanted to have children, and everything was really good," she says.
