Colorado Tries to Revive Cold Cases

For too long, people have gotten away with murder in Colorado, according to a group trying to help families of cold-case (search) murder victims.

And because of that, the faces of the victims from unsolved murder mysteries involving guns are being used in Colorado on billboards near the places they were killed. The hope is that the billboards will trigger memories or someone's conscience — or even greed — in an attempt to find the killers.

In addition, one family in Colorado is offering a huge $100,000 reward for information leading to the arrest of the person who shot their son.

These efforts are part of a nationwide initiative of the Bush administration to reduce gun violence. The program gives states grant money to fight gun-related crimes. In Colorado, the billboard program is run through Families of Homicide Victims and Missing Persons (search), which helps families deal with unresolved murders and long-time missing persons.

In Colorado alone, there's an estimated 1,000 unsolved murder mysteries from the past 30 years. Now, forensic science is so advanced that many experts say these crimes could now be solved if they're reopened.

"You can never know ... someone in this neighborhood knows something about this case," said U.S. Attorney for the District of Colorado John Suthers (search).
