The jailbreak was foiled when a random cell search turned up the hacksaw blades. Sheets tied together to make a rope were also found.
The San Antonio Express-News reported that a girlfriend of one of the inmates testified about giving Casas the bag of tacos. Tiffany Contreras says Casas knew the tacos contained six broken hacksaw blades.
Casas told detectives he thought they were simply tacos.
