(AP) - A Boise attorney and the Idaho Innocence Project are trying to get a new trial for a woman who was convicted of killing both her parents after a fight about her boyfriend. Sarah Marie Johnson was 16 in 2003 when prosecutors said she shot Alan and Diane Johnson at the family's Bellevue home. Fifth District Judge Richard Bevan ruled last year that Johnson's claims of ineffective legal counsel and new evidence didn't warrant a new trial. Now her attorney, Dennis Benjamin with the firm Nevin, Benjamin, McKay & Bartlett, has asked the judge to reconsider. Benjamin told the Idaho Mountain Express on Tuesday that he believes Johnson is innocent. Deborah Whipple, an attorney with the Idaho Innocence Project, is assisting in the case.
