Crime-scene tape marked-off the area where the body of 56-year-old Armando Rodriguez was found dead on Saturday night.
It was not far from the Rio Grande and just minutes from his Brownsville home.
Cameron County Sheriff Omar Lucio said the man died at the hands of his own son.
"He stabbed him several times and then he uses the truck to run over him, Lucio said. He knew good and well that he had the intentions of really killing his father. How much more angry can you get than that when you kill your own family member, your own father?"
According to court documents, 25-year-old Alvaro Rodriguez, who also goes by the alias Alvaro Gonzalez, was upset that his father had locked a door at this home.
They fought all day and Brownsville police even responded to several domestic violence calls made by his mother.
"The most dangerous calls that law enforcement will (respond to), is a family disturbance because by that time, Lucio said, people are already in a heated argument and they are not thinking about anything."
Court documents reveal that the son ran into the nearby brush to hide from police.
That's when his father went after him in his pick-up truck, and with a steel pipe in hand.
When the father approached the son, things took a turn for the worse.
Alvaro Gonzalez allegedly used a green screwdriver to stab his father and then beat him with a steel pip from a 3-ton jack.
"He confessed to have beaten, stabbed, and then he ran-over his father with a truck, Sheriff Lucio said. There were several noticeable lacerations and puncture wounds to the body."
The son drove the truck back home, but on second thought, turned back towards the Rio Grande, Lucio said, to dump the truck in the river.
The San Pedro man allegedly plunged the truck into the Rio Grande River after being sought by Border Patrol agents and then took off his clothes and threw them in a small pond.
U.S. Border Patrol agents in the area, found the truck partially submerged in the river and the suspected murderer not too far from the crime scenes.
A K-9 led police to the father's body dumped in the brush.
Rodriguez TMs bond was set at $250,000. If convicted, he could face five to 99 years behind bars.
