A California nurse was working in the emergency room when she learned a patient dying from a hit-and-run crash was her brother.
Jennifer Medina told KNBC-TV she was working a busy shift at a hospital in Mission Viejo on Friday night when an unresponsive man was brought in.
She said as doctors worked frantically to save the 23-year-old man, a fellow nurse looked for his identification.
Ms Medina said when her colleague found the man's wallet, she immediate recognised it.
When she opened it, she saw his face.
The Orange County Sheriff's Department said Cesar Andres Medina was crossing on a green light in San Juan Capistrano when he was fatally struck by a pick-up truck.
A suspect was arrested in connection with the crash on Saturday.
