The American police say they have found a multitude of explosives at a home in the U.S state of Virginia where eight people were shot on Tuesday. Bomb experts searched the rural property after the suspect Christopher Speight in the shootings gave himself up after an all-night manhunt. Police say they are exploding the devices hidden both in and outside the suspect's house. Medical examiners will try to identify the victims once the area is secured. Mr Speight has been taken to Appomattox regional jail.
