Specifically, police said Nowak confronted Shipman, who was in her car at the Orlando airport, and sprayed something at her, possibly pepper spray.

At first the astronaut was charged with attempted kidnapping and other counts, and a judge had permitted her release on bail. Then, in a surprise move, prosecutors upped the charge to attempted murder, basing it on the weapons and other items they said they had found with Nowak or in her car: a pepper spray package, an unused BB-gun cartridge, a new steel mallet, knife, rubber tubing and large garbage bags.
