NYDAILYNEWS Reports; A Florida woman accompanied by a child trolled the aisles of a Tampa Walmart, constructing a bomb as she went, and tried to blow up the store, police said Tuesday.

Emily Stallard, 37, of Tampa, was charged with several felonies, including attempted arson of a structure, firebombing, contributing to the delinquency of a minor, child abuse and battery on a law enforcement officer, the Tampa Bay Times reported.

It was an alert security guard at a Walmart in Tampa who noticed Stallard cruising the aisles, picking up – and opening – “flammable materials, projectiles and matches,” the Tampa Bay Times reported. And she was shoplifting them, to boot, the Hillsborough County Sheriff’s Office told the Tampa Bay Times.

Stallard then proceeded to fill a mason jar with fuel-grade denatured alcohol and wire brad nails – tiny and nearly headless – and fashioned a wick out of a shoelace. As she was attempting to set fire to the lace with a lighter, the security guard and an off-duty officer who the guard had alerted stopped her, WTVT-TV of Tampa reported.
