STAMFORD - Prosecutors filed an appeal today challenging a judge's decision to grant Michael Skakel a new trial.

A judge ruled Skakel's attorney did not represent him adequately at his original trial in 2002 when he was convicted of murdering his neighbor Martha Moxley in Greenwich in 1975.

The judge said Skakel probably would have been acquitted if the defense focused more on Skakel's brother.

Prosecutors say that more focus on Thomas Skakel's relationship with Moxley would have bolstered their argument that Michael Skakel committed the murder in a jealous rage.
