Story highlights Valedictorian tells classmates she is an undocumented immigrant

Larissa Martinez says she fled Mexico

Larissa Martinez, graduating from McKinney Boyd High School in McKinney, Texas, detailed her difficult journey to her class through a series of "unexpected realities," and ending on her undocumented status.
