FRANKLIN, Ind. -- The family of a woman who died after a pallet of bottled water fell on her at a Kroger store in central Indiana is suing the water bottler, arguing a new eco-friendly bottle design might have contributed to the accident.

The lawsuit filed by the husband of 32-year-old Lori Keen is pending in federal court in Indianapolis. It says that Nestle Waters North America's new bottles used less plastic and couldn't support as much weight as previous bottles.

Keen was fatally injured March 15 when a 4,100-pound pallet of bottled water fell on her in the warehouse of a Kroger store in Franklin. The lawsuit seeks unspecified damages.

Nestle Waters spokeswoman Jane Lazgin said Wednesday the company was still reviewing the circumstances of the accident.
