Large Group of Illegal Immigrants Arrested in Arizona







"Before in remote areas we didn't have the technology or infrastructure or personnel to actively patrol and monitor the more remote areas," he said. "The larger groups are easier to spot so they're getting rarer and rarer. We're getting to the point where it's almost impossible to cross in groups so large."

Cantu said it didn't make sense why smugglers attempted to take last week's large group into the U.S.

He said several smugglers likely were with the group but either got away or successfully blended in with the immigrants and went undetected as smugglers.

"Normally smugglers are the first ones to run, and they'll abandon the group and leave the group to fend for themselves," Cantu said.
