STAMFORD, Conn. (AP) - A judge is expected to rule Monday on whether lawyers for a Massachusetts man charged in the killing of Greenwich real estate mogul Andrew Kissel can present evidence implicating Kissel's ex-wife.

Defense attorneys for 22-year-old Leonard Trujillo of Worcester filed papers last week in Stamford Superior Court asking permission to introduce the evidence.

Judge Richard Comerford said Thursday he will review the motion to see if it contains any sealed items.

Prosecutors say Trujillo was hired by his cousin, Kissel's former chauffeur, to kill Kissel.

The defense motion centers on the hatred Kissel's ex-wife, Hayley Wolff, allegedly had for Kissel. It claims she checked his life insurance policy shortly before his death.

Wolff has denied any involvement in Kissel's death.

Testimony in the trial is set to begin July 13.
