(US Parks Service) (Newser) – A suspect believed to have fired shots at the White House last week is still at large and police believe he may be a threat to President Obama. A semi-automatic weapon was found in a crashed car belonging to Oscar Ramiro Ortega, a 21-year-old Idaho man, CNN reports. Ortega has a fixation with the White House and a criminal record that includes convictions for domestic violence, drug offenses, and assaulting police officers, sources tell ABC. A bullet was found in a White House window after Friday's incident. It had been stopped by ballistic glass behind the historic exterior glass. Authorities believe Ortega has been in the DC area for weeks, repeatedly visiting the Washington Mall, and possibly blending in with Occupy protesters.
