A jawbone found in Milwaukee has been identified as belonging to a 19-year-old woman who was killed and dismembered after a first date.

Sade Robinson's mother, Sheena Scarbrough, said at a news conference Thursday that a pedestrian found her daughter's jaw and teeth on a rock at Warnimont Park in Cudahy.

The Milwaukee County Sheriff's Office confirmed the discovery and told WISN 12 News that testing matched the jaw to Robinson."Our condolences go out to Robinson's family as they absorb this news and reflect on her memory," the sheriff's office said in a statement.
