Did Pfizer Shooting Victim Pull the Trigger Herself?

(MoneyWatch)  Police and Pfizer employees are wondering whether a woman who was shot on a Pfizer campus in Chesterfield, Mo., wounded herself and is making the whole thing up, according to KTVI in St. Louis.

The shooting last Thursday prompted a lockdown of the campus there. Pfizer employees' cars were searched as they left work.

The woman, whose identity has not been released, said she had been grabbed from behind by a man and shot in the foot. Police recovered a weapon at the scene and then began a search of the massive campus, where 1,200 Pfizer employees work. The woman's injuries were not life threatening. She was working as a contractor on new construction at Pfizer.

Since then, police have examined hours of videotape but not come up with an image of the alleged attacker.

KTVI reported this:

With layoffs looming, FOX 2 couldn't find anyone willing to go on camera Tuesday but one employee told us off camera that there is plenty of doubt about how the story was told to police. Detectives can't rule out a fabrication just yet either.

There are no other suspects being looked at. See video of the SWAT team at Pfizer here.
