Police release details in shooting of Portland suspect Michael Reinoehl

New details have emerged in the fatal shooting of Michael Forest Reinoehl, who was accused of gunning down a man during a political rally in Portland.

Law enforcement officers from a federal task force led by the FBI and U.S Marshal Service were conducting surveillance outside an apartment complex in Lacey, Wash., roughly 120 miles north of the Oregon city, when 48-year-old Reinoehl left the building at approximately 7:30 p.m. local time Thursday, officials and law enforcement sources told Fox News.

A Washington-based law enforcement source told Fox News four members had learned that Reinoehl was inside an apartment located within the complex and were waiting for a SWAT team to arrive to arrest Reinoehl when he came out of the house and got into a car. The officers decided to immediately make a traffic stop, the source said.
