Jefferson turned herself into authorities after the incident and is being held at the Baltimore County Detention Center on $350,000 bail.
Cops told the Baltimore Sun that Jefferson and the unidentified victim had been feuding long before the incident. According to police, Jefferson has a child with the victim’s boyfriend.
In addition to injuring the unidentified woman, 19 other people were sent to area hospitals for treatment of respiratory problems caused by toxic fumes from the mixture of household cleaning products.
This is obviously not the type of behavior that we would expect from people at our stores,” Wal-Mart spokeswoman Dianna Gee told the Sun. “And we want to apologize for any inconvenience this may have caused other customers.”
The store was closed for two hours for cleaning.
