INDIANAPOLIS (WISH) — Tito Jackson, a member of the legendary Jackson 5 and a key figure in one of music’s most iconic families, has died at the age of 70.

Known as the quiet but steady force behind the Jackson 5, Tito Jackson, born Toriano Adaryll Jackson, helped bring the group’s groundbreaking success. Along with his brothers Jackie, Jermaine, Marlon and the inimitable Michael, Tito helped define the Motown sound of the late ’60s and early ’70s with hits like “Blame It On the Boogie,” “I Want You Back” and “ABC.”

Although Tito often remained in the background compared to his more flamboyant siblings, his contributions were vital. His rhythm guitar skills added depth to the group’s sound, and his constant presence helped maintain unity during the group’s meteoric rise and turbulent times.

Jackson’s death was confirmed by his family in a statement. “Tito was a beloved brother, father and friend, and his loss leaves a tremendous void,” the statement said. “We ask for your privacy as we mourn the passing of our beloved family member.”

While his brothers ventured out on solo careers, Tito forged his own path, dabbling in blues music and later performing with his band, The Tito Jackson Blues Band. His solo work showed a different side of his artistry, one rooted in deep emotion and a love of playing the guitar.

Already scarred by significant loss, including the tragic death of Michael Jackson in 2009, the Jackson family now faces another heartbreaking chapter. Fans around the world have taken to social media to pay tribute to Tito Jackson’s legacy, remembering him not only as a member of the Jackson 5, but as a pivotal figure in their own musical journey.
