Michael Graf, the younger brother of tennis star Steffi Graf, appears to be living in the flood-control tunnels under the Las Vegas Strip. He also faces an active arrest warrant in Nevada.
Court records show the 55-year-old missed a court hearing earlier this year. The case is tied to a misdemeanor charge.
In recent weeks, Graf has posted several videos and livestreams on Facebook. The footage appears to be recorded deep inside the tunnel system.
In the videos, he looks disheveled and speaks erratically to the camera. He walks past graffiti-covered walls that are familiar features of the tunnels.
Life Beneath the Las Vegas Strip
The drainage network was built in the 1970s. Its purpose was to carry flash flood water away from the Strip.
Over the years, the tunnels have become a shelter for people without homes. They offer protection from summer heat and from local rules that ban sleeping on city sidewalks.
Local outreach groups estimate that between 1,000 and 1,500 people live in the valley’s drainage network.
Before moving underground, Graf reportedly lived in a tent near Lake Mead. His social media posts support this, with videos recorded almost only around the lake until mid-2026.
