This is a fairly long article so I will just include Excerpts:
Deported illegal immigrants return repeatedly
Federal agents took an illegal immigrant to Grant Medical Center in October 2009 to collect proof of his ties to a Mexican-based drug ring.

During his two-day hospital stay, Jose Aranda-Mora supplied the needed evidence - 92 balloons of heroin that he had swallowed before a traffic stop in Richland County.

Three months earlier, immigration agents had deported Mora to his homeland of Mexico. But the free ride home served as no deterrent. Since 2000, Mora has been deported four times, only to return time and again - most recently to Ohio.

A Dispatch investigation revealed that it is common for deported immigrants to return to the United States despite the threat of felony charges.

In another case, Juan Jose Beltran-Coronel's fourth trip to the border with immigration agents came after he was involved in a car crash in Kansas that killed his wife and exposed him as a human smuggler

On 16 other occasions, Beltran was caught in the U.S. illegally and left on his own, court records show.

He served 5 1/2 years in prison and was shipped back to Mexico in 2002. Within three years, he was back, living in Preble County in western Ohio.

For Antonio Galloso, deportation came in 2005. By that time, Columbus police had charged him with domestic violence twice. But Galloso sneaked back to Columbus, where he sexually assaulted a woman.

A Franklin County judge sentenced him to community control - similar to probation. But U.S. Immigration and Customs Enforcement agents got him instead, and federal prosecutors charged him with illegally re-entering the country.

And ICE agents deported Guadalupe Wollum in 2007 after authorities caught her with more than 200 pounds of marijuana in Dayton. It took her a little more than three months to return to Montgomery County, in western Ohio, where federal agents found her again.

These cases illustrate the often frustrating and sometimes overwhelming task that ICE agents face when enforcing immigration laws.

They also show that immigrants can and do find paths back, even though returning to the United States after deportation is a felony that carries a prison sentence of two to 20 years.

All four immigrants eventually were sent to federal prisons for breaking immigration laws. They were sentenced to between four months and six years.

In the polarized debate on immigration, some ask: What took so long for justice?
Nationwide, the number of people prosecuted for coming back illegally after being deported has increased by 175 percent since 2005, according to a report by Syracuse University's Transactional Records Access Clearinghouse, or TRAC, which gathers and analyzes data from public agencies
