Yesterday, two young Wal-Mart workers were tragically shot dead in a Wal-Mart parking lot in Glendale, Arizona. We would like to express our deepest sympathy to those workers and their families.

Have any of you experienced any problems in Wal-Mart parking lots?

From the AP:

Two Wal-Mart employees were shot to death Tuesday as they gathered shopping carts in the parking lot of one of the retail stores in suburban Phoenix, and police later arrested the suspected gunman.

The shootings occurred in the middle of the parking lot, about 75 yards from the store entrance. At one point, a body could be seen in one of the corrals used for collecting shopping carts.

Hours later, police spokesman Mike Pena said a suspect had been arrested without incident in a retirement community in nearby Peoria.

Investigators initially sent a robot to Ed Lui's door, fearing he could still be armed. The man came out with his hands up and was booked on two counts of first-degree murder, Pena said.
