According to ICE:
Woodburn, Ore — The man accused of shooting and killing three people and injuring a fourth on a blueberry farm outside of Woodburn, has been deported from the U.S. six times since 2003.
Bonifacio Oseguera-Gonzalez is accused of shooting and killing 60-year old Ruben Rigoberto-Reyes, 26-year old Edmundo Amaro-Bajonero and 30 year old Katie Gildersleeve. He also shot and injured 27-year old Refugio Modesto-DeLaCruz on June 27th.
He was last repatriated back to Mexico in 2013. But no worries, Obama assures us that our southern border has never been more secure than it is now.
