A suspect has been detained by Mexican authorities in connection with the kidnapping of four Americans, two of whom were killed.

Jose Guadalupe N., 24, was manning the residence where cartel members kept Latavia “Tay” McGee, Eric James Williams, Shaeed Woodard, and Zindell Brown hostage and subjected them to torture.

Guadalupe, a Mexico national, is alleged to be a member of the Gulf Cartel, a local group that is responsible for the kidnappings, but the authorities have not made this information public.

According to Irving Barrios, the state’s top prosecutor, the bodies were found on Tuesday in a wooden cabin in Ejido Tecolote, a rural location east of the Mexican city of Matamoros, Tamaulipas. Woodward and Brown were dead when the Americans were discovered.

McGee and Williams, two survivors, were driven over the Veterans International Bridge to Brownsville, Texas, under the protection of local officials. To receive medical attention, they were brought to Valley Regional Medical Center in Brownsville.

Américo Villarreal, the governor of Tamaulipas, reported that Williams had been shot in the left leg but that his wound was not life-threatening, the fourth victim sustained no injury.

According to the family, the four Americans from South Carolina crossed the southern border so that McGee could have a belly tuck.

On Friday, as they crossed into Mexico from Brownsville, their car was hit by gunfire as they were about to enter Mexican territory. The crew had found itself caught up in a gunfight between opposing drug organizations.

Two of the victims’ bodies were dragged across the pavement looking injured or dead as armed men thought to be members of a Mexican drug gang forced them into the back of a white truck.

The kidnapping and murder of the Americans have only resulted in Guadalupe’s arrest, but detectives are still searching for other attackers.

For the safe return of the kidnapped people and the capture of their captors, the FBI offered a $50,000 reward.
