Lawyers for an Irish nanny charged with murder in the death of a Massachusetts baby are seeking to have charges dismissed based on what they say is prosecutorial misconduct and lack of probable cause.

Aisling (ASH'-ling) McCarthy Brady has been indicted her on a murder charge in the death of Rehma Sabir (REM'-uh suh-BEHR') in January.

Her lawyers accuse Middlesex prosecutors of acting unethically in the way they presented evidence to the grand jury. The defense also contends the case is so weak that it does not meet the low legal threshold of probable cause.

Middlesex District Attorney Marian Ryan said in a statement to The Boston Globe (http://b.globe.com/15QmEjk ) her office is working on a response to the defense allegations, which they will soon file in court.
