"I've known RJ for many years," said LAPD Chief Charlie Beck. "He's a man of great character, a man of great ability, a man of a huge heart. And he demonstrated the passion in his life, which was protecting others in everything he did."
Cottle wasn't the only one lost. Also killed in the same explosion was Lance Corporal Rick Centanni. The two men were both from Yorba Linda. They met each other for the first time in Afghanistan.
And it wasn't just a hometown that they shared. Like Cottle, the 19-year-old Centanni also wanted to work in law enforcement. His father is on the force in Santa Ana.
"I was blessed. He was a great young man," said Jon Centanni, Rick's father. "Everybody loved him."
Centanni was on his first deployment with the Marine Corps. Cottle was in the Marine Corps Reserve. He had already safely served two tours in Iraq before being deployed to Afghanistan. He is the first LAPD officer to die in either war.
"About two years ago, RJ and I and some of the other guys from SWAT went to a funeral in San Diego for a San Diego SWAT officer who had deployed to Iraq and was killed. We went there to support them. When the funeral was over, RJ pulled me aside and said, 'Canaan, if anything happens to me, just let everybody know that I died doing what I love," said LAPD Officer Canaan Bodell.
A memorial service for Cottle will be held next week. The 45-year-old will be buried at Arlington National Cemetery.
