LITTLETON, Colorado (CNN) -- Police are on the verge of arresting a man who may have illegally sold a gun used in the Columbine High School massacre, authorities told CNN on Thursday.

The name of the man and his connection with gunmen Eric Harris and Dylan Klebold were not immediately available.

Steve Davis, a spokesman for the Jefferson County Sheriff's Department, said discussions were continuing with the attorney about "what to do."

Jefferson County District Attorney David Thomas told NBC's "Today" show on Thursday that "there will be an arrest in this case."

Thomas said authorities are discussing the man's surrender with his attorney and it would probably take place in the next two days.

The district attorney said the man would be charged with violating a law against selling handguns to minors. The sale of the gun, a semiautomatic TEC DC-9 handgun, was a "private transaction," he said.

Harris, 18, and Klebold, 17, hiding their arsenal under black trench coats, killed 13 people and wounded more than 20 others at the school April 20 before killing themselves.

They had four guns and also left more than 50 bombs at the school and in their homes. A diary indicates the plot had been planned for a year.

Thomas did not indicate which teen was believed to have bought the gun or how he or they knew the suspect.

The Denver Post reported on Thursday that agents of the federal Bureau of Alcohol, Tobacco and Firearms on Tuesday visited the Blackjack Pizza shop where Harris and Klebold worked. It quoted unidentified sources as saying a pizza delivery driver may have introduced Harris and Klebold to the seller.

The owner of the Blackjack Pizza shop, Christopher Lau, wouldn't comment except to say, "We are cooperating with investigators in every possible way and will continue to do so."
