In this Feb. 22, 2013 photo, signs and plastic flower mark the Falfurrias, Texas grave for the unidentified remains of suspected illegal immigrants discovered in South Texas.

For some, the tragedies are a powerful motivator in pushing Congress to act this year on a larger immigration reform package. (AP Photo/Eric Gay)
