At the scene, the responding deputies found a man's body, who was identified as 31-year-old Christian Castillo from Mission, lying on the roadway.

According to the release, witnesses reported to deputies that Castillo was being followed by a Chevrolet HHR, which was occupied by at least two men.

The suspects exited the vehicle, and one of them hit Castillo multiple times with a wooden board, causing him to fall to the ground, the release stated.

While Castillo was on the roadway, he was hit by a blue Chevrolet Silverado going southbound.

According to HCSO, Silverado was unrelated to the earlier assault and left the scene without stopping.

The Texas Department of Public Safety's assistance was requested to help with the crash reconstruction aspect of the investigation.

Hidalgo County investigators and crime scene specialists responded to the scene and interviewed witnesses, gathering evidence that helped identify the suspects.

The investigation revealed that the suspect's vehicle was registered to the victim's wife, who had previously filed an assault report against Castillo that evening.

Deputies later found the suspect's vehicle and a wooden board with apparent blood stains inside near the intersection of Minnesota Road and Mile 5 Road.

During the course of the investigation, deputies identified the driver of the HHR as Armenta, who is the boyfriend of the victim's wife.

According to investigators, Armenta admitted to being present at the scene along with the second suspect, identified as 32-year-old Jose Maximiliano Flores, who hit Castillo with the board.

Armenta was arrested on charges of manslaughter.

Hidalgo County Sheriff's Office Public Information Officer told ValleyCentral, investigators have issued an arrest warrant against Flores.

HSCO investigators state they anticipate more arrests related to this case.
