Steffi Graf’s Brother Apparently Living in Las Vegas Homeless Tunnels Amid Arrest Warrant

Michael Graf, the younger brother of tennis icon Steffi Graf, appears to be living in the flood-control tunnels beneath the Las Vegas Strip while facing an active arrest warrant. Court records show the 55-year-old failed to appear at a hearing tied to a misdemeanor trespassing charge earlier this year.

In recent weeks, Michael Graf has posted a series of unsettling Facebook videos and livestreams recorded from deep within the channels. In the footage, he appears disheveled, speaking erratically to the camera as he wanders past familiar graffiti-covered walls.

Originally constructed in the 1970s to divert flash flooding beneath the Strip, the vast drainage network has long served as a refuge for the unhoused. The underground system offers shelter from brutal summer heat and sanctuary from local ordinances prohibiting sleeping on city sidewalks.

Local outreach organizations estimate that between 1,000 and 1,500 people live throughout the valley’s drainage network.

Prior to moving underground, Graf reportedly lived in a tent near Lake Mead. His social media activity supports those accounts, showing footage recorded almost exclusively around the lake until mid-2026.

His social media activity ramped up after a misdemeanor trespassing charge led to court-ordered conditions. However, on March 12, Graf was arrested for driving under the influence in Boulder City near Lake Mead, according to Nevada court records cited by the New York Post.

When he failed to appear for a subsequent hearing on March 26, a bench warrant was issued—and remains active.

Strained Family Ties

While much of his rambling footage is difficult to decipher due to degraded audio quality, Britain’s The Sun reported that one video features Graf addressing a strained relationship with his famous brother-in-law, Andre Agassi.

According to the outlet, Graf describes a bizarre physical altercation involving “pinching” Agassi’s chest and executing “pirate moves.”

Born in Germany, Graf moved to Southern Nevada around 2001, coinciding with Steffi and Agassi setting up their primary residence in Las Vegas. While his sister remains one of the most decorated champions in tennis history, Michael has largely lived out of the public eye.

A search of major photo archives returns almost no recent imagery—only decades-old photos of a young Michael in spectator stands, watching his sister dominate the sport.
