NEW YORK (AP) — Two men serving sentences in connection with the 2007 traffic-stop slaying of an NYPD patrolman have been charged with attempted murder in a separate incident.

Dexter Bostic and Robert Ellis were arraigned in Queens Supreme Court on Wednesday, where they entered not guilty pleas.

The officer, Russel Timoshenko was fatally shot July 9, 2007, after pulling the men over for driving a stolen vehicle. His partner, Herman Ian, was wounded but survived.

Authorities say the new charges stem from an incident a day earlier in which Bostic allegedly wounded a man after demanding money from him. Ellis allegedly drove the getaway car.

Bostic is serving a life sentence for murder in the Timoshenko case. Ellis is serving 15 years for weapons possession.
