Carrying a yellow flower to the crash site in Santa Clarita, Calif., on Sunday, where a makeshift memorial has emerged, Gibson broke down into tears at the loss of his friend. In video obtained by TMZ, the 34-year-old actor cries and looks at the candles, flowers and other mementoes left by fans.
Gibson shared an Instagram photo of some of the debris from the crash, which burned Walker's body to such a degree that the Los Angeles Coroner's office will need dental records to officially identify him.
"I will keep your energy with me forever #AshesOfAnAngel fast family around the world we live you and we love you Paul is the heartbeat of this franchise and were gonna see to it that his energy and presence lives on forever #myhearthurtssobad," Gibson captioned the photo.
"My heart is hurting so bad," Gibson said in his first Instagram after the accident.
