SAN ANTONIO, Texas — Cody Huffman can be found all over San Antonio shining a light on the case of Melissa Lucio, the first Latina on death row in Texas. She’s set to be executed on April 27. 

“It’s almost my calling, I feel like, to help somebody like Melissa Lucio who may not have had the best representation initially and is set to be executed next month,” Huffman said. “I wouldn’t be able to live with myself if I didn’t try to help somebody who I believe truly was innocent.” 

He is a law student at St. Mary’s University, which has a well-known law program. He’s not from San Antonio, but he grew up in the Rio Grande Valley, where Lucio was convicted. However, geography is not his only connection to this case. His mother was convicted in a neighboring county. 

“There are just so many ties that kind of overlap these two stories from the individuals that were involved in the forensic analysis,” Huffman said.

So when he’s fighting, it’s like he’s also fighting for his mother who has been incarcerated for seven years. 

Aside from protesting, Huffman and his law school classmates have worked together with the director of the pro bono program to write letter campaigns to elected officials in Cameron County. 

“Have them call the district attorney’s office in Cameron County, the governor’s office, the Texas Board of Pardon and Paroles, with scripts provided as to what we needed them to discuss or relay in their messages,” Huffman said. 

They are also encouraging people to watch the documentary "The State of Texas vs. Melissa Lucio."

Huffman is very hopeful because the Innocence Project, which helps those who are wrongfully convicted, is involved with Lucio’s case. 

“They do it very strictly as to who they choose to represent, so I feel like it’s in my best interest to help individuals like that, who are just...they just need hope,” Huffman said.
