Er, it WAS Friday morning.
It appears it was just a typo. Should have been 'Thursday'. Here is the same piece from ABC News:
"A Wal-Mart worker was killed Friday when "out-of-control" shoppers desperate for bargains broke down the doors at a 5 a.m. sale. Other workers were trampled as they tried to rescue the man, and customers shouted angrily and kept shopping when store officials said they were closing because of the death, police and witnesses said.
At least four other people, including a woman who was eight months pregnant, were taken to hospitals for observation or minor injuries, and the store in Valley Stream on Long Island closed for several hours before reopening.
Shoppers stepped over the man on the ground and streamed into the store. When told to leave, they complained that they had been in line since Thursday morning.
Thanks for the correction. Takes it from “Huh?” to “just plain crazy,” though.
