Marshall police Detective Sonya Johnson said Monday that Christopher Hamilton of Crawford, Ark., allegedly had the hatchet with him when entering the store. Two female workers and a male shopper were attacked early Sunday.
Authorities are trying to determine a motive. Police don't believe Hamilton knows the victims.
Walmart Stores Inc. spokeswoman Betsy Harden says one worker was treated and released while the other should soon be discharged from a hospital. The customer was slightly hurt trying to help the workers and he didn't seek medical help.
Hamilton was being held Monday on three counts of aggravated assault with a deadly weapon with bond set at $225,000.
