A University of North Carolina student who was shot to death by a police officer told a 911 dispatcher he was trying to kill himself and that he had a gun, according to emergency tapes released Wednesday.

Listen: 911 Tape

"I'm trying to kill myself on I-40," Courtland Smith, a fraternity president from Houston, told a Guilford County dispatcher.

Smith was killed early Sunday morning after a confrontation with police following a 911 call during which the 21-year-old repeatedly asked the Guilford County dispatcher to send help.

Archdale police stopped Smith on Interstate 85 south of Greensboro. Officer Jeremy Paul Flinchum, 29, shot Smith after a "confrontation ensued," according to a police report.

Guilford Metro 911 released a recording of the call Wednesday after the assistant district attorney in Randolph County sought a court order Monday to seal the tape. Smith told the dispatcher he had a little to drink that Saturday night and that he was carrying a 9mm pistol in his back pocket. Smith wouldn't identify himself to the dispatcher, saying,

"Everything that anyone needed to know got e-mailed to my parents."

He thanked the dispatcher for talking to him but asked several times over the course of the 15-minute call why the police hadn't arrived to pull him over.

Smith refused the dispatcher's requests to pull his car off the road, but pulled over when he saw flashing lights, according to the call. Smith placed the 911 call in Guilford County, but had passed over to Randolph County by the time police were able to reach him.

When Smith's car comes to a stop, police can be heard in the background shouting, "Stay in the car! Stay in the car!"

"I've got to pull something out, I've got to pull something out," Smith responds in a muffled voice.

The line cuts out after Smith says, "Where the (expletive) do you all think you're going?"

A DKE spokesperson released a statement from the fraternity in response to the 911 call.

"After hearing the 911 tape we were saddened and surprised at what we heard given the last contact Courtland had at the fraternity. The last information we had on Courtland was that when he left a party at the fraternity at approximately 12:30 a.m. and went to his off-campus residence he seemed to be fine," said Chris Rice, DKE spokesperson and alumnus in the statement. "Courtland, who was 21 years old, talked to his roomates at approximately 2:00 a.m. and he sounded normal."

The State Bureau of Investigation is reviewing the incident, which is standard procedure for officer shootings. In the meantime, the officer, Flinchum, was placed on administrative leave with pay, Archdale Police Chief Darrell Gibbs said.

Messages left with the Smith family Thursday were not returned.

A memorial service was held Wednesday at UNC-Chapel Hill, where Smith was a junior and president of the Delta Kappa Epsilon fraternity.

Hundreds attended the service at Chapel of the Cross on Franklin Street. Those who knew Smith best said it's been a tough few days as they try to support each toher and focus on teh good times they had.

"He was goofy, hilarious, awesome to be around," said Ward Minton, DKE member. "Always smiling and always found stuff to do to keep people laughing."

"There will always be a void here," said Harrison McCaskill, DKE member. "We'll always remember him and will keep him in our hearts and prayers a long time."
