The FBI, Homeland Security and other federal agencies are waiting to hear when autopsies will be conducted on two victims of Friday’s kidnapping of 4 U.S. citizens in Mexico.

As of Tuesday evening, Latavia McGee and Eric James Williams were still both at the Valley Regional Medical Center in Brownsville, Texas. Williams had been shot in the leg and underwent surgery, according to the FBI.

Family members said the four had traveled from South Carolina to Mexico last week so that McGee could have a cosmetic procedure done. Mexican authorities believe the shootout and kidnapping Friday were the result of a case of mistaken identity, saying a cartel likely mistook them for Haitian drug smugglers.

After several raids by Mexican authorities, all four victims were found Tuesday, two alive and two dead.

Obviously, Mexico is going to be doing their investigations we have to wait till they release the bodies before they can come back here,” said Jerry Robinette, a retired Homeland Security Investigations official.

Officials discovered the four in a building on the outskirts of Matamoros, toward a beach area called Bagdad, about 40 minutes from the Texas resort area of South Padre Island. Shaeed Woodard and Zindell Brown were dead inside.

McGee and Williams were found alive and then taken to the Veterans Bridge where the exchange took place with the FBI, Homeland Security and other federal agents.

According to former Homeland Security agent in charge in South Texas, Jerry Robinette, regular commerce that goes back and forth will now suffer the consequences of this brazen attack on U.S. citizens.

“This is not good for business if you are the cartel, because they know what happens next, there's going to be additional scrutiny at the ports of entry along the border," he said. "You're going to have people turning over rocks, you're going to have people interviewing, there's going to be a lot of enforcement action to follow and invest a case like this. And sure enough, you are going to find things that they don't, they don't want you to find. So, this is not good for business."

McGee is due to fly back to South Carolina on Wednesday, according to her family.
