Mysterious deaths of two US Border Patrol agents as one is found dead in vacation hotel room after prostitute tryst – and the other kills himself days after trip

The FBI is investigating the deaths of two U.S. Border Patrol agents after their vacation in Colombia.

Jaime Eduardo Cisneros, 54, and Alexander Ahmed, 54, traveled to Colombia together in late May.

But before they returned home, Cisneros was found dead in a Medellin hotel after meeting a woman described locally as a prostitute.

Ahmed then committed suicide on US soil after returning home from the trip, before FBI agents had a chance to interview him about his friend’s death.

Cisneros’ cause of death remains unknown. According to local media, the woman he had been with waved goodbye to him and left his room.

Border police officer Alexander Ahmed, 54, went to Colombia with the officer found dead, but returned alone.  Days after returning to the US, he took his own life

U.S. investigators spent days in Medellin working with Colombian officials to determine how he died.

Officials discovered that his phone and other valuables were missing from the hotel room where his body was found, and that his clothing and suitcase were in “complete disarray.”

His wallet was also emptied.

After his death, Ahmed returned to Texas alone, but committed suicide a few days later.

Ahmed’s body was discovered in El Paso on June 4.

Both men were assigned to the Clint station, just outside Texas’ sixth-largest city, and were close to retirement.

US Customs and Border Protection, the parent agency of US Border Patrol, did not immediately respond to a request for comment from DailyMail.com.

In December, the US embassy in Bogota issued a decision travel warning after eight American men died under ‘suspicious’ circumstances in the South American country in two months.

So far this year, 28 tourists, including Americans, have died in Medellin, Colombian authorities admitted.

Tou Ger Xiong fell in love with the Colombian city of MedellĂ­n for its culture and traveled there often, posting online about women he met.  The Minnesota comedian and activist's body was found in a ravine on December 11 after he went out with a woman he met on a previous trip to the city.

Their deaths range from suicides, illness, drug overdoses and murders.

US officials said American tourists are being targeted in a dating app scheme.

The apps are not mentioned in the government bulletin, but Tinder, Bumble and a third app called Colombian Cupid are the most used dating apps in the country.

“Over the past year, the embassy has seen an increase in reports of incidents involving the use of online dating applications to lure victims, usually foreigners, into a violent robbery or the use of tranquilizers to drug and rob individuals,” embassy officials explained.

Embassy officials urge anyone who is the victim of a robbery not to resist as you are more likely to be killed.

They also advise travelers to Colombia to share their plans with friends and loved ones back home, as victims’ phones are often stolen in an attempt to hide all evidence.

American Tou Ger Xiong made friends in MedellĂ­n during his multiple visits to the Colombian city.  In October, he posted photos of dining with a woman (pictured) at a Korean restaurant and apparently accompanied her to a Karol G concert during his most recent trip, which culminated in his death.

Authorities believe that Americans who fall victim to these types of crimes often come forward.

“These types of crimes are routinely under-reported because victims are ashamed and do not want to continue with the legal process,” the embassy said.

Medellin, infamous as the home of drug lord Pablo Escobar, has been relatively safe in recent years.

However, in the past year, tourism officials in Medellin noted a 200% increase in thefts involving foreigners.

Deaths increased by 29% and most of the homicide victims were Americans.
