Investigators are looking into the possibility that a Border Patrol agent who died in Texas over the weekend may have fallen down a 14-foot culvert, according to
The Associated Press report.
The agent, Rogelio Martinez, died Sunday night after sustaining extensive injuries to his head and body. His partner, who also sustained a traumatic head injury, does not remember what happened, according to the AP.
The FBI is leading the investigation into the incident. The results of Martinez's autopsy are still undetermined.
According to the AP, Martinez was found at the bottom of the culvert, and authorities believe that he may have fallen.
Border patrol agents reportedly check culverts in the area routinely for drugs.
“We are waiting for the investigation to fully determine how those injuries happened,” Rush Carter, a U.S. Customs and Border Patrol supervisor for the region that includes the area where Martinez was killed, told the AP.
Authorities have not said how Martinez died or how his partner was injured. President Trump and some other lawmakers have suggested that the agents were attacked.
In a tweet on Sunday, Trump vowed to bring to justice those responsible for Martinez's death and renewed calls to build his proposed border wall.
According to the AP, a CBP supervisor said reports that the agents were attacked were only "speculation."
