Makarov pistol
The killer was apparently waiting for Nemtsov on a side stairway leading to the bridge. At least six shots were fired, four of which hit Nemtsov; one wound was fatal. According to "Kommersant" sources, the killer used either a standard Makarov pistol or an IZh gas pistol modified for use with lethal ammunition. According to a witness, "a young man named Viktor M., who followed Nemtsov", the killer was a man of height, short haircut, medium build, dressed in jeans and a brown sweater.
