KANSAS CITY, Mo. -- Nearly two years after the deaths of two young friends, police still have few clues about their homicides.

Nathan Buie Sr. and his wife recall getting the call that their son had been shot. At first, they didn't believe it. Their son, Nathan Buie Jr., was a track star at the University of Missouri-Kansas City, an honor roll student on a full scholarship.

Police said Buie and his friend DeMarco Harvey were shot and killed outside the Knights of Columbus early in the morning of July 23, 2006.

Harvey was going into his junior year at the University of Arkansas-Pine Bluff, holding down two jobs to put himself through school.

Investigators said a fistfight broke out in the parking lot at the building near West 83rd Street and Wornall Road. Then guns were pulled and 57 shots were fired into the crowd gathered there, police said. Eleven people were shot. Buie and Harvey were killed.

There were an estimated 200 people there for a party that night, police said. No one has come forward with information that has led to the shooter.

"Silence has allowed the killers to remain on the streets," said Buie Sr.

Both families hope that one day soon something will change and someone will answer their questions.
