Searching for Justice: Morgan Harrington

The pain that Dan and Gil Harrington feel on a daily basis is nearly unbearable. I have known the Harrington's since shortly after their daughter, Morgan was brutally raped and murdered in 2009. They have persevered through the pain -- determined to find the monster who took their gorgeous daughter from them.

Morgan -- a high achieving Virginia Tech student -- went missing from a Metallica concert on October 17, 2009; 101 days later on January 26,2010 her body was found. Virginia State Police uncovered her skeletal remains a few miles outside of Charlottesville. She was 20 years old.

Three years later, no arrests have been made. But, we do know that DNA from a vicious sexual assault in the Washington, DC suburbs a few years prior matches DNA in Morgan's case.

Not a day goes by that Dan and Gil don't call Morgan's cell phone to simply listen to her voice -- a voice they yearn for, a voice they miss.

Please -- watch Dan and Gil below and do the right thing. If you have any information about who killed their daughter -- please come forward. That's what you would want if your child had been murdered.
