It was 8 p.m. on a Friday in 1988, and newly licensed lawyer Chris Tritico was still at work at Haynes and Fullenweider in Houston when he took a call from a potential client.

Tritico met with the caller, a Houston Independent School District teacher who thought there might be a warrant out for his arrest, and gave the teacher some advice. That next Monday morning, Tritico says, he got a call from Gayle Fallon, president of the Houston Federation of Teachers, who asked him to represent the teacher.
