“One of his first targets on the ground from the tower was a member of the terrorist SDS organization.”
I was a student on campus that day. I have never heard that about any of his victims.
I ran across it in a magazine in the dentists office sometime in the past year - I think it was D Magazine - something upscale like that.
But since I can’t track it down online, here’s a less legitimate source. It was the pregnant girl:
“Claire Wilson James was born in Texas in 1947, and was raised in Dallas. Introduced to Dr. Martin Luther King at age 12 and trained in nonviolent resistance by James Farmer at 16, she worked for the Student Nonviolent Coordinating Committee (SNCC) in the Mississippi voter registration drive of 1965. She was active in Austin Students for a Democratic Society (SDS) when she was the first person shot from the tower — with her boyfriend and unborn baby both being killed. “
