Family of slain Chicago area Uber driver sues Walmart

CHICAGO (AP) - Relatives of a suburban Chicago Uber driver who was fatally attacked while on the job has sued Walmart, where authorities say the driver's teenage attacker stole weapons just before the killing.

The family of Grant Nelson filed a wrongful death lawsuit Monday in Cook County against the retailer and two other companies overseeing its security.

Authorities have charged 16-year-old Eliza Wasni in Nelson's death, saying she stole a machete and knife from Walmart early on May 30 and then got into Nelson's car and brutally attacked him.

The lawsuit claims two Walmart employees or contractors stood near the door as Wasni exited. The lawsuit alleges they were negligent because they failed to stop the teen and ask her any questions.

In a statement, Walmart says its associates "acted properly."
