The body of University of Central Florida graduate student Nicole Ganguzza, 26, was discovered last Wednesday near Blanchard Park, located off the Econ Trail. Police said she was abducted while she went for a night jog.

An Orange County sheriff's official said the persons of interest came forward and spoke with detectives about the Ganguzza case after their sketches were released.

They were then cleared in the case.

Investigators are still searching for two other persons of interest in the case (pictured).
