Crime scene investigators were back at the ranch Tuesday, presumably looking for more clues. They searched a heavily wooded area across the street from where those shots were fired.
A man believed to be the victim's son told us he did not want talk. Authorities say his father, Veronico Trujillo, 64, was shot once in the head inside his pickup truck as he sat waiting for the front gate to open around 6pm Monday.
Trujillo is a businessman who owns a tortilla company in north Houston.
In Spanish, a worker at the business told us Trujillo is a good man, that he provides them with work. That's very important, said the employee.
Back in the Montgomery County neighborhood near the several hundred acre ranch where Trujillo and his family lived, residents are still shaken.
"We were all on lockdown in our neighborhood here with our kids," said neighbor Rosa Besler. "We were very scared."
While a motive has yet to be revealed, frightened neighbors don't believe this was a random crime.
"It sounds real suspicious that they knew him and then when they ran into the woods, it seemed to me like they probably had an escape plan," said neighbor Mary Bradley.
Investigators say they want to talk to Trujillo, who is recovering from his gunshot wound. He is listed in critical, but stable condition at Memorial Herman Hospital.
