Savannah Mercedes Lopez is arrested after allegedly striking a 62-year-old man in a hit-and-run accident (via Bexar County Sheriff’s Office).

A woman who was apparently out on bond on a DWI charge is accused of striking a homeless man on the street and causing his death by internal decapitation.

Savannah Mercedes Lopez, 27, was arrested for allegedly striking the man in San Antonio, Texas, on Monday night. The victim showed no external signs of the injuries that killed him, officials said. At a press conference Thursday, Bexar County Sheriff Javier Salazar said that the man, who has not been publicly identified, was discovered by a pedestrian the following morning.

Salazar said that there were “no outward signs of injury” when the victim was first spotted, but an autopsy revealed that his internal injuries were “severe” — including blunt force trauma “that consisted of an internal decapitation.”

“Internally, it was as if he was decapitated,” Salazar explained. “Everything in his neck area was severed except for the skin, so it kept it all intact.”
