Investigators have not yet determined a motive for the shooting. Police believe he may have been trying to eventually make his way to the federal courthouse.

Perez was not a current or former employee of the bank, Isaac said at a press conference Thursday.

He had been living in Cincinnati since 2015 at seven different addresses, Isaac said. He had been issued several citations in the area but did not have a local criminal history.

Perez also has a \"brief criminal history\" in South Carolina and Palm Beach, Florida, Isaac said.

Court documents show that Perez filed two lawsuits against NBC Universal, Inc. and CNBC Universal Media in the Southern District of Ohio earlier this year, alleging that the oranizations used his cell phone harvest and broadcast his personal information.

No such broadcasts appear to have been aired, ABC Cincinnati station WCPO reported.

ABC News' Rachel Katz and Morgan Winsor contributed to this report.
