A package that exploded in the hands of a Scottsdale employee Thursday traveled through the U.S. mail — one of only two mailed explosives in the country in two years, a spokesman for the investigation said.
The U.S. Postal Inspection Service assumed the lead role in investigations into the bomb that injured Don Logan and his assistant when it detonated about 1 p.m. Thursday inside the city’s human resources building at 7575 E. Main St.
"The first thing we look at is motive, and we have to look at all angles. The sky is the limit on what this could lead back to," U.S. Postal Inspector Bob Maes said. "Who knows what motivates somebody to try to kill somebody?"
Maes said that as of Friday he did not know of any threats against Logan, 48, director of the city’s Office of Diversity and Dialogue. The package was addressed to Logan.
The U.S. Postal Service is offering up to $100,000 for information leading to the arrest and conviction of a suspect.
"We are working jointly with Scottsdale police, the Bureau of Alcohol, Tobacco and Firearms, the Federal Bureau of Investigation and assisted by the Arizona Department of Public Safety, Mesa police, Phoenix police and Glendale police," Maes said.
Logan, hospitalized for burn and shrapnel injuries to his hands and forearms, is expected to fully recover, city spokesman Mike Phillips said Friday. Logan’s secretary, Renita Linyard, 52, who was struck in the face with shrapnel, also is expected to recover.
A third employee was treated at the scene.
Scottsdale City Manager Jan Dolan said employees remained in shock.
"People are on edge a little bit," she said. "These employees are very well-known . . . People have a deep concern for them. Certainly they’re concerned about their own safety. But, they want to continue to do their jobs. And, they’re angry. They’re angry that this could happen to someone they know."
City offices, including human resources, were open Friday.
Tom Mangan, ATF spokesman, said Logan was fortunate to have survived the blast that blew a basketball-size hole in his desk. Shrapnel as large as 2 1 /2 inches peppered the floor, walls, ceiling and furniture surrounding Logan.
"If this had detonated outside, we would have had debris that traveled 100 yards," Mangan said. Maes said remnants of the package indicated it had been sent through the U.S. mail, but would not say if it had a postmark. The package had a Valley return address on it.
Authorities said they believe this was not part of a mass mailing.
Bomb technicians from across the Valley collected evidence from Logan’s office until 10:30 p.m. Thursday before sending bomb debris to a forensic laboratory in Dulles, Va., for analysis.
Scottsdale police Sgt. Doug Dirren on Thursday described the package as 8 inches by 11 inches. Mangan said he would not characterize it as a letter bomb. Details about the package and the explosive device were not released.
As with all bomb investigations, technicians will try to reconstruct the bomb and compare its composition to a national database, Mangan said.
"The devices offer unique signatures of the people who construct them," he said.
Maes said a bomb was sent through the U.S. mail last month to a New Jersey resident. The country did not have any mail bombings in 2003. Thursday’s bomber could face multiple charges at local, state and federal levels — including a sentence of up to 20 years, if convicted, on one charge of sending an explosive device through the mail.
