SAN DIEGO -- The leader of an alien smuggling ring that transported more than 100 undocumented immigrants across the border over a seven-year period was sentenced Friday to 63 months in federal prison and ordered to forfeit a house and $598,775 in cash.

Marisela Castro-Juarez of Chula Vista pleaded guilty May 15 to bringing undocumented aliens to the United States for financial gain and engaging in financial transactions of more than $10,000 with money derived from alien smuggling.

She was sentenced by U.S. District Judge Janis Sammartino.

Between 2001 and 2006, the 38-year-old defendant made deposits of more than $590,000 generated from the smuggling operation into her personal bank account and used the profits to purchase a home in the South Bay, according to the U.S. Attorney's Office.

The charges against Castro-Juarez stem from an investigation dubbed "Operation Blackjack," conducted by agents from U.S. Immigration and Customs Enforcement and U.S. Customs and Border Protection.
