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.

Tips in the case had slowed recently but the sketches released Tuesday night and put new life into the investigation, Local 6's Jessica D'Onofrio said.

Crimeline's Barbara Bergin said people are calling with a variety of information.

"They're talking about possible names, who that could be," Bergin said. "(Also) 'I saw that same guy at this location,' things like that."

Detectives said the faces in the sketches were either seen in the area before or after Ganguzza went missing.

Investigators said the men in the sketches are not suspects but only persons of interest.

They would like to just rule the men out in the investigation, D'Onofrio reported.

Anyone with information about the case is urged to call Crimeline at 800-423-TIPS.
