Doctor seeks new trial in wife's slaying

BOSTON -- A once-prominent Massachusetts doctor convicted in the 1999 killing of his wife is asking the state's highest court to grant him a new trial, saying the jury should not have been allowed to hear about his secret sex life.

The Supreme Judicial Court will hear arguments Friday in an appeal by Dr. Dirk Greineder. He was a well-known allergist when he was convicted of beating his wife with a hammer and slashing her throat after she discovered his trysts with prostitutes and his fascination with Internet pornography.

Greineder argues numerous other grounds for a new trial, including a claim that his trial lawyers should have challenged DNA evidence presented by prosecutors.

Greineder claims his wife was killed by an unknown assailant after the couple separated during a walk in a Wellesley park.
