Henry, 26, was killed after he fell out of the bed of a pickup truck driven by his fiancee, Loleini Tonga, during what police have called a domestic dispute. Police are investigating, but no charges have been filed.
Tonga, wearing sunglasses, repeatedly paused to gather herself as she spoke to hundreds of mourners at his funeral, including Henry's teammates, who filled the stands at a suburban New Orleans events center. Tonga professed eternal love for Henry and promised to raise their children the way he would have wanted.
"Can't nobody know the way I'm feeling right now. No one can explain the relationship that me and Chris had. In six years of knowing each other - through hard times, good times - we loved each other very much," she said. "People say I helped change his life. No, he changed mine."
Mourners clapped briefly as Tonga slowly made her way back to her front row seat.
NFL commissioner Roger Goodell, Bengals players, coaches and members of the front office, as well as other NFL players, including New Orleans Saints running back Reggie Bush, were among those who attended. The Bengals wore black buttons on their lapels with Henry's No. 15. Many from Henry's hometown of Belle Chasse wore red ribbons with a small photo of Henry that read: "In loving memory" and "Chris 'Slim' Henry."
Speaking before the service, Goodell said Henry would be remembered as a good person who made mistakes, then sought to better himself.
