SAN DIEGO--A grieving man who lost his family to an FA-18 Hornet Jet Fighter crash Monday that destroyed their University City home spoke out for the first time since the deadly accident.

At a news conference today, Dong Yun Yoon, 37, thanked the San Diego community for their prayers and support.

"I thank all the people who are praying for me and for my family," said Yoon, surrounded by friends and family. "Nobody expected a horrible thing to happen. I can't believe they are not here no more."

Yoon's brother, sister, pastor and other members of Korean United Methodist Church, comforted him while he spoke to reporters near the crash scene.

While Yoon spoke, military fighter jets from Marine Corps Air Station Miramar sailed through the sky, a reminder of that tragic day in San Diego.

Earlier that afternoon, search personnel found the remains of Yoon's daughter Grace, 15 months old. Yoon thanked the fire department, police, and other emergency personnel for searching for his family.

Also killed in the crash wasYoon's 36-year-old wife, Young Mi Yoon, 2-month-old Rachel, and his mother-in-law, Kim Suk Im, 60. Yoon's mother-in-law had arrived from Korea to help take care of the young children.

Yoon and his wife were married four years ago. The family had just moved into the house on Cathers Street two months ago.

"I believe my wife and two babies and mother-in-law are in heaven with God," Yoon said. "And I know God is taking care of them."

Yoon described his wife as a "lovely wife and mother" who loved him and his babies. "I just miss her so much."

Yoon said the pilot of the jet fighter was not at fault for the crash. "Please pray for him not to suffer from this accident," Yoon said. He said the pilot did the best he could to avoid crashing in the neighborhood.
