The little boy reached into Veronica J. Rutledge’s purse and her concealed gun fired, Kootenai County sheriff’s spokesman Stu Miller said. The woman was shopping on Tuesday with her son and three other children, Miller said.
Rutledge was from Blackfoot in southeastern Idaho, and her family had come to the area to visit relatives.
The woman had a concealed weapons permit. Miller said the young boy was left in a shopping cart, reached into his mother’s purse and grabbed a small-calibre handgun, which discharged one time.
Deputies who responded to the Wal-Mart found Rutledge dead, the sheriff’s office said.
“It appears to be a pretty tragic accident,” Miller said.
The victim’s father-in-law, Terry Rutledge, told The Associated Press that Veronica Rutledge “was a beautiful, young, loving mother.”
The woman’s husband was not in the store when the shooting happened at about 10.20 am (local time) on Tuesday. Miller said the man arrived shortly after the shooting. All the children were taken to a relative’s house.
The shooting occurred in the Wal-Mart in Hayden, Idaho, a town about 64 kilometres northeast of Spokane. The store closed for the rest of the day.
Brooke Buchanan, a spokeswoman for Wal-Mart, said in a statement the shooting was a “very sad and tragic accident.”
