Cincinnati police have identified the slain gunman in a downtown high-rise shooting that left three other people dead and two more wounded.
Police Chief Eliot Isaac says authorities don't know why 29-year-old Omar Enrique Santa-Perez opened fire at the 30-story headquarters of Fifth Third Bancorp.
Isaac says police believe he's lived in the Cincinnati area since 2015.
He says the shooter carried a 9mm handgun, and carried an estimated 200 rounds or more of ammunition.
Isaac says police are still investigating, including searching his apartment 15 miles west of Cincinnati. That search turned up nothing.
Court records indicate Santa-Perez sued NBC Universal twice this year, claiming his personal information was stolen and broadcast on MSNBC. Both suits were thrown out.
The Cincinnati Reds say there will be a moment of silence by the team and fans before Thursday night's game with the San Diego Padres. The stadium is a short walk from the site of the shooting.
