BINGHAMTON, N.Y. -- It's 8:48 a.m. on Friday April third and Binghamton University professor Mary Muscari sends an email to local media entitled: "Ten years after the Columbine massacre: optimism and deep concern"

Less than two hours later, Wong opens fire and kills 13 innocent people at the American Civic Association.

An eerily ominous email from Muscari, an expert in small-town and school shootings, but her academics hardly prepared her for that Friday morning.

"Even though I'm an expert, it's still shocking when it happens in your own backyard."

Muscari is trying to study the shootings and while she says we may never know why Wong did what he did, his early April timing is consistent with other shooters.

Many suffer from depression and seasonal affective disorder, as spring breaks, they stay depressed.

"One of the theories is that everyone feels better and they don't, it adds to the list of things that predispose them to doing this type of event," said Muscari.

And while she says some of Wong's actions follow patterns of the Virginia Tech and Columbine shooters, many of those unanswered questions will stay unanswered.

"It's where you die, how you die that says something. We'll never know what happened. It's like the ultimate icing on the cake of getting back at people that they'll never know. We'll never know the full story because he took it with him."

But Muscari's extensive experience has taught her one thing for certain.

"Every crime victim needs to hear no matter how awful a crime is, those three words, you can heal."

Muscari will also chair a conference in early May that was supposed to focus on mental health issues, but now has been expanded to include the Binghamton shootings.

Muscari, a forensic nurse by training, mostly works with juvenile offenders, but also recently wrote an article on adult and youth mass murders.
