Texas valedictorian reveals she's undocumented in graduation speech

MCKINNEY, Texas -- A valedictorian dropped a bombshell in front of thousands at her graduation in north Texas - she revealed she's an undocumented immigrant.

"I decided to stand before you today and reveal these unexpected realities, because this might be my only chance to convey the truth to all of you that undocumented immigrants are people, too," Larissa Martinez said in her speech.

Martinez graduated from McKinney Boyd High School with a 4.95 grade point average.

During her speech, she revealed her mother had been in an abusive relationship and left Mexico City with her two daughters in 2010.

"They are my reason to live. So that's why I do it. It's hard," Deyanira Contreras, Martinez's mother, said of her children.

Martinez told local station WFAA her mother's strength kept her going. She now has a full scholarship to Yale and is hoping to enter the pre-med program and ultimately become a neurosurgeon.
