'Human smuggling is a violent criminal enterprise that puts the safety of our communities and our country at risk,' Acting Deputy Chief Scott Luck said.

'We are committed to using the wealth of resources, technology and expertise at our disposal not only to disrupt the current activity, but to identify and dismantle the criminal organizations behind it.'

Border Patrol was able to identify the criminals and gang members by searching CBP and FBI biometric databases.

The databases electronically compared a live-scanned fingerprint against a nationwide database of biometrically indexed records.
