That morning, Jared Loughners father saw him take a black bag out of a car trunk, Sheriff Clarence Dupnik told the AP.
The father approached Loughner, and he mumbled something and took off running, Dupnik said. The father got in his truck and chased his son as he fled on foot...
The Sheriff told that story about the black bag, on the basis of an interview with the father. Unfortunately the Sheriff is not reliable, but it seems likely that that’s what the father told him.
Did the father know what was in the black bag? Who knows? But why would he chase after the kid into the desert, unless he suspected something pretty bad?
