The weapons Eric and Dylan carried and the clothing they wore during the massacre.
Eric’s clothing: Black fatigue-style pants, a white T-shirt inscribed with the words Natural Selection on the front, black baseball cap with the letters “KMFDM” on it (worn backwards), and a black trenchcoat (duster). Wore a black fingerless glove on his right hand and black combat boots.
Eric’s weapons: 10-shot Hi-Point model 995 carbine rifle on a strap (under coat), Savage-Springfield 67H 12-gauge pump shotgun he called ‘Arlene’ (named after a Doom character - initially in one of the duffels carried to the top of the grassy knoll – stock and barrel sawed off, reducing the entire gun to 26 inches).The sawed-off weapons, each around 30 years old, were so short that firing repeatedly from them caused the hands of the gunmen to bleed when fired on the practice range initially. The teens apparently acclimatized to the weapons over the months preceding the shootings. Both shooters also carried several knives. They named their pipe bombs. Four bombs are mentioned on Eric’s website, along with their specs. 'Vengeance’ (pictured at bottom) and 'Atlanta’ were found at the Klebold residence when police searched it.

Dylan’s clothing: Black cargo pants, a black T-shirt that said Wrath in red across the front, black baseball cap (worn backwards), and a black trenchcoat (leather duster, really). Also wore a black fingerless glove on his left hand and black combat boots. Had a red medallion on his left boot bearing a sickle and hammer. Black suspenders were found close to his body.
Dylan’s weapons: Intratec TEC-DC9 (9-mm semi-automatic handgun) attached to a strap slung over his shoulder (under coat), Savage 311-D 12-gauge double-barrel shotgun (barrel sawed down to approximately 23 inches, initially half-hidden in Dylan’s cargos).
