Saw a bright light change directions then disappear

My husband (sales Director), dad (retired police chief) and myself were outside after putting the kids to bed. Not positive on timing. Looking at the sky we were looking for satellites among the stars. Backs facing Long Lake (East), we were looking up facing West. The Big Dipper was behind us (we had to turn heads to view it). We all noticed this single bright light (brightest “light” in the sky) moving slowly, then stopped before changing directions then disappearing all together. The skies were clear, no clouds. We all saw it were all shocked! Eliminating planes and satellites, we assumed it was some sort of UFO.
