VAN HORN -- The autopsy report is complete for the border patrol agent killed near Van Horn, but questions remain into who or what killed the federal officer.
Rogelio Martinez, 36.
Agent Rogelio Martinez -- known to his friends as Roger – died in the line of duty in November 2017.
Tuesday evening, the El Paso County Medical Examiner released an 11-page official autopsy report.
The cause of death: “blunt injuries to the head.”
However, the manner of death is “undetermined.” That means physicians could not determine how the deadly injuries were caused.
But the autopsy report does reveal an interesting pattern to the deadly injuries -- the blunt trauma all happened on the right hand side of Agent Martinez’s body.
The right part of his skull suffered a semi curricular fracture. The right side of his scalp had two cuts, and his right upper jaw bone was broken.
Moving down his torso, physicians found his right shoulder had a large wound and his right collar bone was fractured. In addition, six ribs were broken.
We talked to emergency room physician Dr. Sudip Bose about the autopsy report.
"It’s impossible to conclude what exactly caused that blunt trauma and that’s because all you see is the injury pattern,” Dr. Bose explained. “Then you have to put that together with the entire context -- the entire picture."
The FBI says fellow Border Patrol agents found Agent Rogelio Martinez and Agent Stephen "Michael" Garland severely injured in a culvert next to Interstate-10, about 12 miles east of Van Horn, at approximately 11:20 PM on Saturday, November 18th.
It's not clear why Martinez and his partner were along the I-10. U.S. Customs and Border Protection only said in a statement that they "were responding to activity."
Martinez died a few hours later from his injuries.
The National Border Patrol Council, a union for the Border Patrol, has maintained someone attacked Martinez.
While the Culberson County Sheriff has said, he believes the agent may have been accidentally sideswiped by an 18-wheeler.
Meanwhile the FBI -- the lead investigating agency -- has only called it a possible assault.
The FBI is offering a $50,000 reward for information leading to the resolution of the investigation and the State of Texas is also offering an additional $20,000 reward for the investigation.
