Agent Rogelio Martinez died of head injuries, manner of death undetermined
The autopsy report for Rogelio Martinez showed he died of blunt injuries to the head.
CBS4 obtained a copy of the report Tuesday afternoon. It also states he had blunt injuries on his eyes, lacerations on his scalp, and fractures to his shoulder, ribs and clavicle.
The manner of his death is "undetermined," according to the report.
Authorities are still trying to determine exactly how Martinez died on Nov. 19, 2017.
According to FBI agent in charge Emmerson Buie Jr., agent Martinez and agent Stephen Garland were found in a culvert area near Interstate 10, about 12 miles east of Van Horn.
The two agents received traumatic head injuries and other physical injuries, and they were taken to a hospital in Van Horn, said Buie.
Their injuries were so severe, they needed advanced medical care, and the agents were airlifted to a hospital in El Paso, the FBI said.
Martinez died from his injuries and Garland was released from the hospital but says he does not remember what happened to them.
A reward of up to $70,000 is being offered by the FBI and the State of Texas for information on the incident.
The FBI is also extending its search to several states to find information on the death of Martinez.
The agency set up billboards asking for information. Those billboards will be visible in Southern California, Arizona, New Mexico and Texas until Dec. 8.
U.S. Customs and Border Patrol Official Rush Carter said all the agency can confirm is that the two agents were injured and that a joint investigation with the FBI will hopefully determine how that happened.
Buie said the FBI is the lead agency investigating this "potential assault on a federal agent officer."
"We are aggressively investigating all leads from the public in regards to this investigation that is ongoing," said Buie.
Authorities continue to investigate the "crime" scene where the two agents were found and the Van Horn and Fort Stockton area, said Buie.
There are no no leads in the case. CBS4 contacted the FBI to see if Garland has been questioned again and a spokeperson said the agency had no comments at this time.
