Posters hanging on storefront windows with photographs of the 21-year-old Penn State student, who has been missing for over a week now, are asking anyone with information to call police and keep watch for her.

Search and rescue teams scanned the area surrounding her apartment complex Friday in hopes of finding the woman friends describe as outgoing and happy, and sometimes spontaneous.

The photographs on the posters depict the smiling face of Cindy Song — a face that has not been seen in over a week. Friends and family have not heard from her since the early morning hours of Thursday, Nov. 1.

The Centre County Sheriff's Office Search and Rescue team went out to look for Song on foot in the area surrounding her apartment complex Friday.

"We went out and searched the wooded and grass areas around her apartment," said Mike Lohr, a volunteer for the Sheriff's Office search and rescue team. "We searched until sunset."

Lohr said they called volunteers from the Elk County search and rescue team and also had help from the Alpha Fire Company in the quest to locate any clues that could give them a lead into her disappearance.

"We didn't find any clues . . . but we do know that she is not in that area," Lohr said.

Lohr could not comment on what they are going to do next.

"We're pretty much doing what we can," Lohr said.

Craig Hall, the commander for the Centre County Sheriff's Office search and rescue team said they searched around the College Park apartment complex but found no trace of her.

As of now, they are on stand-by for police in the search for the missing woman.

"As far as I know, the Ferguson Township Police have a few areas they are looking into," Hall said. "We're on stand-by."

The Ferguson Township Police Department, in charge of the investigation, have called Song's disappearance "suspicious" and have not ruled out foul play. They continue to search for her whereabouts.

Song was last seen wearing a short white skirt, a pink top, brown boots and a red hooded coat.

Song has not attended any of her classes since her disappearance and has not shown up to work. She has not accessed any of her credit cards or bank account.

Anyone with information is asked to call Detective Brian Sprinkle of the Ferguson Township Police at 814-237-1172 or 1-800-479-0050.
