Yes there was:





Mark Manes sold a TEC-DC9 semi-automatic handgun to the shooters. He was sentenced to six years in prision (4 months after the shooting). He served about 19 months before he was released to a halfway house. He was released in 2002 under electronic monitor and been denied parole three times.





Philip Duran introduced Mark Manes to the shooters. He is a graduate of Columbine and worked at Blackjack pizza with Dylan and Eric. He pleaded guilty and is serving a 4 1/2 year prison sentence in 2000. He was parolled after 3 1/2 years.





Robyn K. Anderson who purchased two shotguns and 9mm rifles for the shooters had no formal charges brought against her.
