A classmate of the man accused of shooting Congresswoman Gabrielle Giffords this morning describes him as “left wing” and a “pot head” in a series of posts on Twitter this afternoon.
Caitie Parker did not immediately respond to our request for an interview, but her “tweets” in the hours after the shooting paint a picture of Jared Loughner as a substance-abusing loner who had met Giffords before the shooting. She says, Loughner described the congresswoman as “stupid and unintelligent.”
We’ve confirmed that Parker and Loughner went to school together at Mountain View High School in Tucson and that both attended Pima Community College, so her claims of knowing Loughner seem to be legit.
