A fire chief says crews detonated four explosives linked to a gunman who took three hostages at Discovery Communications headquarters in Maryland.

Montgomery County Fire Chief Richard Bowers said Thursday that officials took the devices from a home.

They were in addition to four devices that hostage-taker James J. Lee had brought with him during the hostage ordeal on Wednesday in Silver Spring, just outside the nation's capital.

Also, Police Chief Thomas Manger says Lee was carrying starter pistols, not handguns as police had previously reported.

Bowers says investigators are still looking for a vehicle that was owned or operated by Lee.
