MMA Fighter Guilherme Vasconcelos Cause Of Death Revealed

Guilherme “Bomba” Vasconcelos — an MMA fighter who competed in the UFC and Bellator, and dated Demi Lovato — died by suicide, according to newly-released documents.

TMZ Sports obtained the case report from the October 15 incident … which state cops were dispatched to an Illinois home around 9 AM after a woman reported finding Vasconcelos in the garage.

After reviewing security camera footage … cops determined Vasconcelos took his own life the night prior around 11:45 PM — and was not discovered until the following morning.

A search of the house recovered several vials of anabolic steroids, with two mostly empty and two unopened. A suicide note was not discovered.

According to a toxicology report … it yielded only one positive finding — caffeine.

Over the course of his MMA career … Vasconcelos racked up a record of 10-6. He and Lovato were first spotted together in 2017 during New Year’s Eve festivities after several months of dating.

Guilherme’s uncle, Walter, mourned the loss of his nephew at the time … saying, “We were looking forward to your visit for Christmas, which will no longer happen. Life is fleeting, and we woke up to this devastating news. What a time we live in.”
