According to the Alaska State Department of Law, Mary Anne Henry, a longtime and high-profile state prosecutor, passed away Sunday at a hospital in Portland, Ore. She was reportedly being treated for a respiratory illness.

Henry was a state prosecutor for 28 years. During that time she prosecuted some of Alaska’s most notorious criminals, including Joshua Wade in 2003.

Wade was accused of murdering Della Brown. Henry delivered the opening statements in that case but had to later abandon her role in the case after suffering a severe asthma attack.

In 2006, Henry was named head of the Office of Victims’ Rights. She advocated for crime victims for nearly a year before being named Deputy Director of the Department of Law’s criminal division. She retired from that post two months later.

Henry was 60 years old.
