DailyBulletin.com - Marine Cpl. Douglas Jose Marencoreyes, 28, a Chino resident, died Sunday in Iraq while participating in Operation Iraqi Freedom, the Department of Defense announced Wednesday.

Marencoreyes, a reservist assigned to the Light Armored Vehicle--Air Defense Battery of the 4th Light Armored Reconnaissance Battalion, was killed when the large transport truck he was riding in rolled over in the Iraqi desert just south of Al Samawah.

Marencoreyes was based out of Camp Pendleton.

Department of Defense officials said in a statement that the incident is under investigation.

Marencoreyes' family could not be immediately reached late Wednesday, and officials at Camp Pendleton were unavailable for comment.

Rep. Gary Miller, R-Brea, on Wednesday called Marencoreyes a hero and hailed him for his courage and commitment to serving his country.

"The void Corporal Marencoreyes has left in this community is vast," Miller said in a statement.

"Words and medals cannot make up for his absence. But in his death, he has come to symbolize all that we love in America. Those with whom we have reluctantly taken up arms against hate America because of its ideals of democracy, economic prosperity, diversity and freedom. Corporal Marencoreyes embodied those ideals in his work and life."
