Brett Michael Mahaffey, age 35, of Chicago, passed away on February 19, 2026. He was born on March 2, 1990, in Oak Lawn, Illinois, to Gina Mahaffey (Danca) and Richard Mahaffey.
Brett traveled extensively throughout Indiana, Missouri, and Illinois. Although he did not graduate from a traditional school, he carved out a successful career in the IT field, working for notable companies like Apple. His determination and skill allowed him to thrive even without a formal degree.

Brett would do anything for anyone he met, leaving a lasting impact on the lives of those around him. His love for his pets, including a cherished pet gecko, his childhood cat Lily, his childhood pet bird Sami and Mika, his father's dog, was also a defining aspect of his personality.
