An Omaha man pleaded guilty to conspiracy to commit robbery in the September 2010 death of Pizza Hut deliveryman Christopher Taylor.
Larry Fountain, 20, will be sentenced in July. He faces up to five years of probation or 1 to 50 years in prison.
Fountain and Marcus Robinson - who is awaiting sentencing -- each were charged as accessories in the deadly robbery.
Fountain allowed Bryton Gibbs and Dontavis McClain to use his cell phone to call Pizza Hut to order the pizzas.
Both Fountain and Robinson, 18, have said they believed Gibbs and McClain would take Taylor's cash but had no idea they would kill him.
McClain shoved Taylor into the apartment and Gibbs stabbed him twice in the back after luring him to a vacant apartment near 89th and Ida Streets on the pretense of buying pizza.
They then left him to die. Gibbs, 18, is serving a 100-year sentence. McClain, 21, is serving a life sentence.
Taylor, 33, was a computer whiz and pacifist who took a job delivering pizza and rejected jobs in the computer industry because he didn't want to work for a defense contractor or anyone who might be involved in killing someone.
Fountain answered with firm "yes sirs" when Judge Mark Ashford asked him if he understood his rights. He told the judge he graduated from Central High School in 2009.
Asked how he pleaded to conspiring to commit robbery, Fountain said: "I am guilty."
Said his attorney, David Herzog: "It's just typical teenage folly where he hands his phone to two thugs. . . (But) my client will tell you that he knew or should have known that that phone call was made for the purpose of extracting money from (Taylor)."
In return for his cooperation and guilty plea, prosecutors dropped a separate charge of robbery.
