By Joseph A. Slobodzian In a courtroom packed with 75 police officers, a Philadelphia judge this morning ruled he would review a motion to try separately the two men charged in the May 3 killing of police Sgt. Stephen Liczbinski.

Common Pleas Court Judge Benjamin Lerner heard argument on the severance motion involving Eric DeShann Floyd, 34, and Levon Warner, 40, and then asked the prosecutor and two defense attorneys to submit briefs outlining the relevant Pennsylvania law on the question.

Assistant District Attorney Mark Gilson and defense attorneys Gary S. Server and William L. Bowe will submit briefs before the next hearing before Lerner on Jan. 7.

Lerner granted defense motions to dismiss the attempted murder charges against Floyd and Warner involving witnesses menaced with a gun during the bank robbery and escape that ended with Liczbinski's killing in a cafr stop and Almond and Schiller Streets in Port Richmond.

The courtroom was packed with the police officers as well as the family of the 39-year-old slain officer, one of four Philadelphia officers killed this year in the line of duty.
