I was able to find the article doing a google news search.
This is the story/article I was looking for.

Raley, reading from a police report, said [Paula Hoopes] was taking revenge on the neighbor, Steve Bowles, who she thought was responsible for vandalism at [Anita L. Jackson]'s mother's house nearby.
Jackson was also at Bowles's house that night, asking him to stop the alleged vandalism. Then, when she and Bowles heard glass shatter, she believed the real vandal was outside, Raley said. She got a shotgun from her mother's house and went out to the field, where she found Bowles pummeling Hoopes's friend, Jane Woods, Raley said. Then, Jackson saw a dark figure bolt toward Bowles and she fired one shot, Raley said.
First-degree assault, [Theodore Weiner] reasoned, would likely result in a sentence of five to 10 years under Maryland's sentencing guidelines for Jackson, an ex-Marine who once served at the White House and has no prior criminal record. Raley also could have ignored the guidelines and given Jackson up to 25 years.
