He is survived by her and his son, Brayden.
An autopsy will be performed on Jan. 15 to determine the cause of death.
"It's something unexplainable, do not know what may have motivated him to do so," Zingano's manager, Jorge Guimaraes said. "We were together and he was fine, had plans and a lifetime ahead. It's a tragedy. I'm going to Denver today to assist the Cat, who is devastated, does not know what to do."
Zingano went 6-0-1 in his brief MMA career, including two victories after turning pro in 1999.
He defeated Michael Miller twice in 1996, to go along with wins over Lane Andrews and Jeff Combs.
In 1998, Zingano won the Gracie National Jiu-Jitsu Championships and was awarded the purple belt.
In 2001, he won his brown belt and began focusing on teaching his BJJ skills to other Jiu-Jitsu students. Many of his students won various championships all over the world.
Zingano kept training Brazilian Jiu-Jitsu and MMA during his teachings and finally received his black belt in 2004.
All classes at Team Zingano - Black House MMA Broomfield and Brighton schools were cancelled after the news came out of his passing, and classes will resume tomorrow, Jan. 15.
No official word yet on funeral arrangements for Zingano, but more details will surely emerge as the day goes on.
Thoughts and prayers for Cat and the entire Zingano family on this day.
