This section deals with the gear and weapons the Columbine High School shooters had. This also includes the Columbine bomb count and information about the 20-pound propane bombs and diversionary devices Eric Harris and Dylan Klebold used.

(according to the autopsies)

Dylan Klebold clothing -- Black battle dress uniform (BDU) cargo pants, a black T-shirt that said Wrath in red across the front, black Boston Red Sox baseball cap (worn backwards), and a black trench coat (technically an oiled leather duster). Klebold also wore a black fingerless glove on his left hand and black combat boots. He had a red medallion on his left boot bearing a sickle and hammer. Black suspenders were found close to his body.

Eric Harris clothing -- Black fatigue-style BDU pants, a white T-shirt with the words Natural Selection in black 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. Had a web ammo vest on over the T-shirt.

Both wore BAR utility belts which held pouches filled with shotgun shells and they carried CO2 cartridge bombs ("crickets") and clips of 9 mm bullets in their pants. Both also had match strikers taped to their forearms to easily light their bombs, many of which had clusters of matches around the fuses.


Firearms the Columbine gunmen carried:
(according to CNN's coverage of the Columbine Report)

Eric Harris fires his shotgun at Rampart Range
Dylan Klebold guns: Intratec TEC-DC9 (9-mm semi-automatic handgun) attached to a strap slung over his shoulder (under coat), Savage Arms Stevens 311-D 12-gauge side-by-side double-barrel shotgun. Barrel sawed down to approximately 23 inches, initially half-hidden and carried in Dylan's cargo pants.

Eric Harris guns: 10-shot Hi-Point model 995 carbine rifle on a strap (under coat), Savage-Springfield 67H 12-gauge single-barrel pump action shotgun he called 'Arlene', named after a Doom character. He carried it in one of the duffel bags the shooters took to the top of the grassy knoll outside Columbine's west entrance. Stock and barrel sawed off, reducing the entire gun to 26 inches.

The sawed-off shotguns, each around 30 years old, were so short that firing them repeatedly caused the hands of the gunmen to bleed when used on the practice range. Both shooters also carried several knives with them, but didn't use them. 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 the house.

Info from CNN:

Only two shots can be fired from a double-barreled shotgun before the shooter must reload by breaking the barrel open, manually inserting two new rounds, and closing the gun. A pump shotgun can be fired as fast as the gunman can pump and shoot. It shoots much faster than the double-barreled type because spent shells are ejected and a live shell manually slides into place. A gunman can shoot five rounds with the pump shotgun before the weapon must be reloaded.

Eric Harris and Dylan Klebold both carried lots of homemade bombs of various types and sizes. Before the shooting, Klebold brought one of the pipe bombs to Blackjack Pizza where he and Harris worked, trying to impress coworkers. His manager, former friend Chris Morris, made him take it out of the restaurant for fear that it would go off.

Both gunmen carried knives as well. Klebold wore a Cobra knife on his belt on the left side and had a switchblade knife in his pocket. Harris wore a boot knife on his belt and had a Khyber Pass machete Bowie knife taped to the back of his leg. Both of those knives had an "R" carved into their handles.

(sourced from the Columbine Report as well as CNN's coverage)
There were a total of 99 explosive devices found by authorities that Harris and Klebold made. 76 were found at the school along with 2 diversionary devices found close to the campus. There were 13 found in the shooters' cars and 8 more located at their homes.

On the Basement Tapes, the gunmen talked a lot about the bombs they had amassed. On April 3, 1999, Harris describes having 6 timer clocks, 39 crickets, 24 pipe bombs and napalm that they're working on which they stored in a freezer. The napalm was problematic as it never worked the way that they wanted it to, yet they were determined to have it with them during their attack. A later journal entry Harris wrote claimed that they had stockpiled 53 crickets and super crickets.

The weekend before the tragic assault, they bought 2 propane tanks. They purchased another 6 the morning of April 20, 1999. Eric Harris was seen on CCTV at a Texaco gas station purchasing one of the Blue Rhino tanks at 9:12 a.m. They used the propane tanks to make 8 bombs. The two duffel bag bombs they left in the cafeteria commons were each constructed from a 20-pound propane tank, pipe bombs, and containers of gasoline. The diversionary backpack bombs left in the field behind Columbine were smaller propane tanks rigged with pipe bombs, gasoline containers, and spray paint cans. They placed 2 of the 20-pound propane bombs in their cars along with several containers of gasoline throughout the vehicles. There were 8 pipe bombs in Klebold's car and another one in Harris'. The explosives were rigged timers that ultimately failed to go off correctly.

Two diversionary bombs were placed off campus, one in an open field south of the school between Ken Caryl and Chatfield avenues and the other at Wadsworth and Elmhurst. The one in the field partially detonated, starting a fire that required Littleton Fire Department. The other diversion, consisting of two pipe bombs and a timer, failed to detonate.
