"His father was telling me that it was just always his dream to be a deputy," said Harris County Sheriff Ed Gonzalez. "He worked extremely hard every step of the way whenever there was another milestone that he needed to reach, another step that he needed to advance."

In 2018, Diaz fulfilled that dream, and his family could not have been more proud. Gonzalez recalled how they bragged about his accomplishments to everyone they met.

"Our academy has a lot of rigor to the program, but he passed every step successfully and graduated in October of last year," said Gonzalez. "We were there at his pinning ceremony and he was just very proud."

Diaz excelled as a deputy and was a well-liked by both his supervisors and colleagues. Gonzalez said everyone at the Sheriff's Office was impressed by his work ethic and passion for the job.

"We're out there to serve and protect, and that's exactly what he was doing -- living his passion out there this morning when he was out assisting others," said Gonzalez.

The sheriff is asking everyone to keep Diaz's family in their thoughts and prayers.
