Olympic Gymnast Simone Biles’ Brother Arrested in Triple Homicide

Tevin Biles-Thomas, brother of Olympic gold medalist Simone Biles, was arrested on Thursday in connection with a triple homicide, reports TMZ.

Biles-Thomas, who is currently serving in the Army, was taken into custody at Fort Stewart in Georgia.

Police tell TMZ that a fight broke out at a New Year's Eve party at an Airbnb in Cleveland when some uninvited guests arrived. Biles-Thomas allegedly opened fire. Two men died at the scene and another died in the hospital. Two others were injured.

In a 911 call obtained by the site, partygoers tell the dispatcher that someone started shooting and that the victims were “on the floor” and “they're both dead.”

Now, a Cuyahoga County Grand Jury has indicted Biles-Thomas, 24, on six counts of murder, three counts of involuntary manslaughter, five counts of felonious assault, and one count of perjury.

TMZ points out that in Ohio, a defendant can be separately charged with “purposely killing” and “knowingly killing” a person, which resulted in the six murder charges.

Biles-Thomas will be extradited from Georgia to Ohio before his September 13 arraignment.

Simone, who was born in Columbus, Ohio, has been open about her family's past struggles. Her parents were unable to care for her and her siblings — Tevin, Adria and Ashley — and they were placed in foster care. Simone and Adria were later adopted by their grandfather Ron and his wife Nellie, while Tevin and Ashley were adopted by Ron's sister Harriet.

The gymnast has four Olympic gold medals and made history earlier this month when she landed a double-twisting, double somersault in competition at the U.S. Gymnastics Championship.

NBC News reached out for comment, but Simone's reps have not responded. On Thursday night, she tweeted without further explanation, “eating my feelings don't talk to me.”
