A gay couple from Chicago who were living in Mexico City have been found dead in a grave that included two other bodies, per Chicago ABC affiliate WLS.

Zafar Padamsee Mawani and Guillermo Jaffet Hidalgo Ortiz had been missing since May, per WLS. The couple had only recently moved to Mexico in October and were living in a neighborhood in the southern part of Mexico City. The bodies were found on June 17 in a wooded area on the outskirts of Mexico City, per People.

The couple went missing on May 20 while trying to get equipment from a contractor for Mawani’s mother, who is living with Alzheimer’s, per CBS News. People with knowledge of the case said that there had also been unusual withdrawals from the couple’s bank accounts, per NBC Chicago and the Associated Press.

“It was horrible, because in Mexico so many people go missing every day,” Maggie Reynoso, a friend who used to style Ortiz, told CBS News.

Reynoso said that “they were going everywhere, dressing very glamourous, even though we told them to be safe.” She continued, “Guillermo … doesn’t think that anybody would do any harm,” she said. “Somebody who did this to him doesn't have a heart.”

Over 130,000 people are currently deemed missing or have disappeared in Mexico, per the Guardian. While the disappearances began to surge in the 2000s, they have increased by more than 200% in the last decade.

Five people, including a former police officer, were arrested in connection with the four bodies that were found together, according to People. The former officer, identified only as Yesenia V., was the alleged leader of a kidnapping and robbery gang.

GLAAD released a statement in memory of Ortiz and Mawani on Instagram.

“Our hearts are with everyone who loved Guillermo Ortiz and Zafar Mawani, a Chicago couple who were found killed in Mexico after they were missing for several weeks,” the post reads. “May Guillermo and Zafar rest in peace.”

Several people under the post spoke in their memory.

“They were two of the absolute best humans,” one person wrote. “Brought so much joy and light to this world. I am better for knowing them. Their story doesn’t end — it lives on in all those who knew and loved them. We must carry their light forward and spread awareness to the horrific crisis happening in Mexico. Currently 133,000 missing people- and counting?!? Most families don’t get the closure we did. Horrific.”

A GoFundMe set up for their families is looking for funds to help with investigation, transparency and accountability efforts, legal consultation, a burial and a memorial for the couple, travel for the family, administrative expenses and resources for Mawani’s mother.

Homicide has dropped 40% under the presidency of Claudia Sheinbaum, who has pledged more support in finding the tens of thousands of missing people.

“What we want is to find the disappeared,” she said in April, per the New York Times. “And we are reinforcing the institutions of the Mexican State to better prevent and respond to this tragic crime.”

About 22,000 missing people were found alive last year, the highest number of people found after disappearing in a single year, per the Times.
