Mourners gathered Wednesday for the funeral of the man shot and killed by a federal agent at a McDonald’s restaurant in Waikiki.

Many people wore black and purple shirts bearing Kollin Elderts’ picture as hundreds spilled out of a chapel at Hawaiian Memorial Park in Kaneohe.

His full name, Kollin Kealii Elderts, was printed on some of the shirts, while others bore the words, "Family First," which friends said Elderts had tattooed on his chest.

"He was the class clown," recalled high school classmate Jerica Kalama, 23. "He just liked to cruise, hang out and just have fun. I just think this whole situation is crazy. I don’t think he deserved to get shot."

Details of the deadly encounter between the construction worker from Kailua and agent Christopher Deedy from Arlington, Va., remain unknown. Deedy is charged with second-degree murder and using a firearm in the commission of a felony. He posted $250,000 bond and was released two days after the Nov. 5 shooting.

Elderts and Deedy were involved in an argument at the Kuhio Avenue restaurant when the shooting occurred.

Elderts, 23, was shot in the chest and was taken to a hospital, where he was pronounced dead.

Elderts, who bled to death from the single gunshot wound in his chest, had a blood-alcohol level of 0.12 percent, the city Medical Examiner’s Office said.

Elderts’ burial came as Oahu recovered from the international spotlight of the Asia-Pacific Economic Cooperation gathering.

"Do you think if APEC never came to the island, he would still be here?" said Hana Werner, 37, a family friend of Elderts’. "Whenever they mention APEC, this is the first thing I’ll think of. I’ll flashback to Kollin."

The killing inspired a 70-person march last week during APEC. On the conference’s opening day, marchers held signs saying "APEC Kills" and "Justice for Kollin" as they walked from Old Stadium Park in Moiliili to the Hawai‘i Convention Center, where ministerial and senior officials met.

State Department spokeswoman Victoria Nuland has said she can’t comment on the investigation but the State Department was cooperating with law enforcement.
