PORTLAND (AP) — A Maine prosecutor has been suspended from practicing law for 30 days, but her suspension won’t be implemented if she completes additional legal training.

The Maine Board of Overseers announced the suspension Thursday against Hancock County Assistant District Attorney Mary Kellett in the first disciplinary proceeding ever filed against a Maine prosecutor.

At a hearing Monday, Kellett admitted making improper statements in her closing argument, withholding evidence and interfering with defense subpoenas while prosecuting a former Gouldsboro man in 2008 and 2009 on a charge of raping his wife.

Under an agreement with the Board of Overseers, Kellett’s suspension has been suspended on the condition she complete additional legal education on prosecutorial ethical and professional responsibility issues.
