Her picture remains posted on downtown business windows and campus bulletin boards. She appears in newspaper articles and news broadcasts. But the smiling photo that has become all too familiar to us remains the only sighting of missing Penn State student Cindy Song in 12 long, frustrating months.

A year ago tonight, the integrative arts major was celebrating Halloween at a costume party at a downtown club, just as many other Penn State students will be doing tonight. She moved on to drop by a few apartments and a convenience store before a friend dropped her off at her West Clinton Avenue apartment around 3:45 a.m. Nov. 1. She hasn't been seen or heard from since.

Today is a day to remember. Today is a day to recommit -- recommit to finding out what happened last Halloween. Let us mark this anniversary by finding the answers that Song's family and friends have been desperately searching for.

On Tuesday, Pennsylvania State Police, at their first news conference about the case, made a plea for the public to think back.

So, please, take a moment to remember where you were last Halloween, what you might have seen and what you might have noticed since Song's disappearance.

Someone in the State College area must know something that can help investigators, even if the small detail or vague recollection seems unimportant to him or her. Any hint or clue is more than what we seem to have to go on now.

Police are asking for information from anyone who noticed someone act strangely or behave suspiciously following her disappearance. Police are looking for anything from health changes, such as sleep disorders or significant weight change, to lifestyle changes, such as unexpectedly changing jobs or residences or suddenly becoming overtly religious.

Don't let this case remain at a standstill. Don't let another year go by with no answers.

In the past 12 months, no solid evidence has been made public, and the few leads the case did seem to have went nowhere. Witnesses have undergone hypnosis. A psychic volunteered her services. The case was broadcast nationally on an unsolved crime show.

But still, we wait for answers. We wait for Cindy to come home.
