HOUSTON - The guns seized after the deadly shootout in Waco have the potential to breathe new life into unsolved crimes around the country.

The Bureau of Alcohol, Tobacco, Firearms and Explosive's Houston office is taking the lead on tracing all of the guns found to determine if any can be connected to cases that go well beyond the Waco area.

"We're initiating firearms traces on all the firearms that were recovered," said Rob Elder, ATF special agent-in-charge.

Elder said at last count, more than 100 firearms have been recovered; everything from pistols to rifles.

"We don't know, at this point, if those weapons could have been used in other shootings, other homicides," said Elder.
