Silvio Horta, creator of ABC's hit series Ugly Betty, has died in an apparent death by suicide.

The 45-year-old Emmy-winning screenwriter and showrunner, who was openly gay, was found dead with a gunshot wound at a hotel in Miami, Florida, this Tuesday, Variety reports. Anonymous sources close to Horta told the outlet the gunshot wound was self-inflicted. Reps for the Hollywood vet confirmed his death to Variety, although his team declined to comment on the circumstances surrounding Horta's passing.

Horta was best known for bringing Ugly Betty—ABC's beloved four-season dramedy adapted from a Colombian telenovela called Yo soy Betty, la fea—to English-language audiences in the U.S. The series, which garnered Horta multiple Emmy wins and starred actress America Ferrera as Mexican-American fashion industry newbie Betty Suarez, ran from 2006–2010.

It was also heralded for being queer-inclusive at a time when so few primetime television shows were: Ugly Betty had a roster of LGBTQ series regulars and guest characters, including queer fashion assistant Marc St. James (Michael Urie), Betty's gay nephew Justin Suarez (Mark Indelicato), and trans character Alexis Meade (Rebecca Romijn).

On Instagram, Ferrera posted a touching tribute to Horta, whose talent and creativity "brought me and so many others such joy & light."

Other celebrities followed suit, including fellow Ugly Betty alum Michael Urie and Pose actor Johnny Sibilly.

According to his IMDB page, Horta's most recent project was 2015's The Curse of the Fuentes Women, a made-for-TV movie he wrote.

Rest in peace, Silvio.
