Investigators said the man's family lives nearby and likes to hang around the area, so when someone recognized him they initially believed he had a seizure — but police said he has head and neck trauma.

To study the best way to administer the seizure medication, midazolam, so that fewer children arrive at emergency departments with an ongoing seizure: Baylor College of Medicine, Texas Children’s Hospital, the Houston Fire Department Emergency Services, Children’s Memorial Hermann Hospital, and UT Health are forming a study called PediDOSE to determine the best way to stop them.
