According to the station, officers said Fobbs took time during the beating to say, "I feel like killing someone," before continuing the beating until the victim was dead.

Police said security guards in the station made their way to the scene, but it was too late.

The victim's name has not been released, because the medical examiner's office has been unable to notify his family, according to KENS.

Fobbs is being held on $150,000 bond.
