LITTLETON, Colorado (CNN) -- As a grief-stricken Colorado town buried more students slain in the Columbine High School shooting, authorities Tuesday said they are investigating reports that one of the teen-age shooters and his friends tried to buy a machine gun and a pistol with a silencer.

Family and friends of shooting victim Matthew Kechter gathered Tuesday morning at a local church to pay their last respects. Other memorial services were planned Tuesday for Kyle Velasquez and Corey DePooter.

Meanwhile, Jefferson County Sheriff Department officer Jeff Schrader told CNN Tuesday that authorities had interviewed a Colorado Springs gun dealer who reported that one of the two students responsible for last week's massacre at the school was among five teens who tried to buy a machine gun from him.

Mel Bernstein, owner of the Dragon Arms gun shop, told investigators that four teen-age boys dressed in trench coats, including Eric Harris, and one teen-age girl came to his store in early March.

Harris, 18, along with Dylan Klebold, 17, killed 12 classmates and a teacher in a hail of bullets and pipe bombs at Columbine High School April 20 before the two killed themselves.

Bernstein said Harris and his friends tried to buy an M-60 machine gun and a pistol equipped with a silencer. He said he declined to sell the guns to Harris because he was too young. When a young woman in the group tried to buy them, saying she was 18, he escorted them from the store.

Bernstein said the incident was captured on a surveillance videotape that he turned over to federal authorities.

"They were real mopey, like punk kids with the makeup on, like punk rockers," Bernstein said. "To me, it was just another bunch of kids who wished they could own everything they see on the wall here. This is like Toys R Us to them."

Bernstein said Harris "was doing all the talking."

Police: Klebold's girlfriend bought 2 guns

Meanwhile, police said the girlfriend of Klebold bought at least two guns used in the attack, according to two Denver area newspapers. The woman was questioned Monday and authorities described her as a witness, not a suspect.

She bought them at a Denver-area gun show soon after her 18th birthday in November, according to investigators quoted in the Denver Rocky Mountain News and The Denver Post.

Prosecutors said the weapons may have been purchased legally.

District Attorney Dave Thomas said prosecutors are not sure what knowledge she had about how the guns would be used. But Jefferson County Sheriff John Stone acknowledged it was possible that she did know how Klebold and Harris planned to use the guns.

Others could be charged

Investigators are still investigating whether anyone besides Klebold and Harris was aware of their plans in the days and weeks leading up to the attack.

Authorities have said Klebold's girlfriend, the suspects' parents or others could be charged as accessories if the district attorney's office determines they knew about the attack beforehand.

"We're looking at a fairly large number of people still. People that were very close to these individuals," said Mark Pautler, the chief deputy district attorney. "But we don't have anybody that we can say were additional individuals at this time."

Stone said three boys who were arrested near Columbine on the day of the attack have not been cleared in the case.

"I'm suspicious of their story," Stone said. "They are not out of the woods in this one yet."

Diary of death

Also Monday, authorities said Klebold and Harris had aimed for an even bigger blood bath, plotting to kill hundreds of students, and then to hijack a plane and crash it into New York City. Investigators cited a diary they found that was kept by Harris, which revealed that the attack on the school was planned for more than a year.

The attack's bold, bizarre nature led to speculation that the gunmen might have been taking drugs, but toxicology tests revealed no drugs or alcohol in their bodies, the county coroner's office said.

Columbine's campus remained closed on Tuesday to everyone except bomb squads and investigators.

Columbine teachers were due to report for duty Tuesday at nearby Chatfield High School, where armed sheriff's deputies and parents have been assigned to guard the doors.

Classes to resume after last funeral

The students of Columbine will begin classes at Chatfield on Friday instead of Thursday as planned.

Columbine Principal Frank DeAngelis told CNN the reason for the delay is that the last of the funerals for the victims will be held Thursday, for student Isaiah Shoels.

The entire Denver area observed 30 seconds of silence Tuesday at 11:21 a.m. local time (1:21 EDT), the time the attack began a week ago.

Many still recovering in hospitals

Ten students injured in the attack remained hospitalized Tuesday. Doctors expect some to have long recovery periods.

Casey Ruegsegger, 17, underwent a five-hour surgery Monday at St. Luke's Presbyterian Hospital for multiple gunshot wounds to her right shoulder and hand. She was recovering in fair condition later that night.

Lance Kirklin, 16, remains in critical condition. He suffered gunshot wounds to the face, chest and legs, and underwent 15- hours of surgery on his face Saturday.

Valeen Schnurr, 18, was released Monday from Swedish Medical Center where she had undergone surgery for multiple gunshot and shrapnel wounds, including nine to the chest.

Sean Graves, 15, is in fair condition and has been moved to a multiple trauma rehabilitation unit.
