An autopsy conducted by the Mecklenburg Medical Examiner reveals that NFL wide receiver Chris Henry died of blunt force trauma to the head due to falling from the truck driven by fiancee Loleini Tonga.

A Charlotte-Mecklenburg police spokeswoman says Tonga pulled over after Henry fell off to assist him. Though the incident was deemed an “accident”, police have not yet cleared Tonga, reports USA Today.

Meanwhile a friend of Tonga’s is stepping out in defense of the 25-year-old mom. “I know people will say, ‘Why didn’t she stop?'” Lori Williams told the paper. “We don’t know … but in the times that I knew Loleini — and I knew Loleini — she would not harm anyone.”

Henry’s funeral is schedule for next week Thursday in his native of Belle Chasse, Louisiana. The Cincinnati Bengals team is expected to attend.
