Katherine Russell labored 70 to 80 hours a week as a home health care aide while her husband Tamerlan Tsarnaev plotted the Boston Marathon bombing with his brother.

Russell, who has now been left alone to raise her three-year-old daughter, was totally unaware of her husband's evil plans, her attorney Amato DeLuca told AP.

"When this allegedly was going on, she was working, and had been working all week to support her family," DeLuca said.
