Nineteen hours later, around 9:30, there was another attack, about eight miles from the first one; the second occurred at West Belden and North Nordica.

Police say a sexual predator may have been watching his would-be victim before striking. He attacked from behind.

Police say the suspect punched the woman in the face, assaulted her, then ran, heading south on Nordica.

The suspects’ descriptions differed in both attacks.
