In December 2017, Santa-Perez filed a suit against NBCUniversal Inc. and TD Ameritrade Holding Corporation in Hamilton County Common Pleas Court. He sought $5.1 million in punitive damages claiming NBC Universal harassed him by eavesdropping on his personal electronics and that TD Ameritrade colluded with NBCUniversal to make that happen.

In June 2018, he filed a suit against CNBC Universal Media, LLC and TD Ameritrade in U.S. District Court seeking damages of $3.3 million. He claimed the two businesses “maintained electronic watch on communication devices owned by Plaintiff.”

A magistrate judge recommended that lawsuit be dismissed five days after it was filed.

Cincinnati Police Chief Eliot Isaac said Thursday that investigators did not know of a motive but that they were looking into “mental health issues” involving Santa-Perez.
