Houston police and federal authorities confirmed Tuesday that a pipe bomb sent to the home of a local oil executive was meant for his wife and not him.
Vennie Wolf, 58, was injured Friday evening when she opened a shoebox-size package that shot out shrapnel and nails.
As they chased leads, officials Tuesday said they believed the incident in northwest Houston was an isolated one. But they refused to discuss the investigation's progress or why Wolf may have been targeted by the bomb.
"It's an ongoing investigation," said Rob Elder, assistant special agent in charge at the Houston office of the Bureau of Alcohol, Tobacco, Firearms and Explosives, which is looking into what happened along with the Houston Police Department.
Curiosity won out
The package had arrived outside Wolf's home in the 2100 block of Seamist Court a few weeks earlier.
Authorities do not think the package was brought there by the U.S. Postal Service, but they're not saying where it came from.
Wolf was hesitant to open the package when it arrived because she didn't know who it was from, officials said, but she later opened it out of curiosity.
Wolf was taken to Memorial Hermann-Northwest Hospital with non-life-threatening injuries. She was later released and is now recuperating, police said.
Speculation about the bombing has run rampant in Wolf's neighborhood, which neighbors said has always been quiet and safe.
Some neighbors said the box had arrived disguised as a box of chocolates, but police declined to confirm that.
The shutters were drawn at the home Wolf owns with her husband, James Brock Moore III, and no one answered the door Tuesday.
Moore did not return a phone message at Adams Resources Exploration Corp., where he has been president since 1998.
Glenn Beck weighs in
The bombing caught the interest of the national news media, too. During a monologue Monday, conservative pundit Glenn Beck speculated the bombing could be the work of unspecified "radicals."
He also suggested the mainstream media were purposely not reporting it.
Wolf and Moore appear to have kept a low profile in Houston. The couple is listed in University of Houston records as making a small donation to the university's engineering program, which Moore graduated from in 1964.
