Pipe Bomb Detonates at Oil Exec's Home

A seemingly anonymous gift left on the front porch of a Houston home owned by an oil company executive has the city's affluent population of oil profiteers on edge this weekend, after that package exploded and seriously injured a 62-year-old woman.

Neighbors of the victim told an ABC News affiliate in Houston that the bomb was disguised as a box of chocolates in a gift bag, left on the home's doorstep around Thursday.

Instead, it contained what authorities described as a pipe bomb carrying a load of thumb tacks and nails. When she opened the package on Friday evening, standing on her back porch around 6:30, it resulted in shrapnel embedded across the woman's face -- injuries police said were not life-threatening.

"It wasn't immediately clear whether the house was targeted, however, Eyewitness News found out the home is owned by an oil company executive," the ABC affiliate further noted.
