After more than a dozen officers walked the highway looking for evidence Wednesday, police said Thursday it was not the collision with the Cadillac that took Rodriguez's life.
"Further investigation into this incident has revealed evidence to support that the deceased was a victim of homicide, unrelated to the vehicle crash," police said.
Homicide investigators are asking that anyone who may have seen Rodriguez interacting with another vehicle please contact investigators at 972-237-8790.
