HOUSTON, Texas (KTRK) -- David Lopez Zuniga has repaired air conditioners for dozen years.
He lives in a mobile home in Houston's southside with his family, and doesn't know anything about elections.
However, Zuniga now finds himself in the middle of a bizarre election fraud case that's attracting national attention.
That's because on Tuesday, former Houston Police Department Captain Mark Aguirre was arrested and charged for running Zuniga off the road and pointing a gun at his head in an attempt to prove claims of a massive voter fraud scheme in Harris County.
"He tried helping him," said Zuniga's step-son Jonathan Reyes, while helping his father translate when ABC13 talked to the family on Wednesday. "Then (Aguirre) took out the gun on him. We didn't know this man. Don't even know if he was a cop or not. And we've never seen him before."
