A New Jersey man who was distraught and angry over not being able to take his daughters to a One Direction concert was sentenced to 8 months in federal prison Tuesday for calling in a bomb threat before the boy band's July 5 performance at Hersheypark.

The phone call that William H. Klein, a 47-year-old divorced dad and former Federal Aviation Administration official, made to Hershey Entertainment and Resorts caused quite a ruckus, investigators said.

What Klein said, according to U.S. Attorney Peter J. Smith, was, "If One Direction plays tomorrow, the stadium will blow up." That prompted a pre-concert lockdown of the stadium, while a bomb sweep was performed and the bags of all of the concert patrons were checked, Smith said.

One Direction did perform, though, before a packed crowd of screaming, mostly preteen, tween and teenage girls.

Smith said investigators from Derry Township police and the FBI traced the threatening call to a New Jersey number, which was found to be attached to a pay phone outside a 7-Eleven store in Northfield. Klein was identified as the caller through video surveillance footage from the store, Smith said, and he later pleaded guilty to an interstate communication with threat to injure charge.

In addition to the prison term, U.S. Middle District Judge Yvette Kane ordered Klein to spend 2 months under house arrest with electronic monitoring after his release, followed by 22 months of probation.

Assistant Federal Public Defender Thomas A. Thornton had sought a time-served prison term for Klein, who has been held in the Dauphin County and Franklin County prisons since his arrest in September.

In a sentencing memorandum, Thornton attributed Klein's threat to mental health problems, a desperate desire to bond with his 10- and 14-year-old daughters, a failed attempt to get tickets for the One Direction gig and horrific judgment.

Thornton wrote that Klein, who had repeated child custody disputes with his ex-wife, tried to get tickets through a friend and told his very excited daughters that he was taking them to the concert. The friend didn't come through, however, and Klein's other attempts to get tickets for the sold-out performance came to naught.

So what Klein hoped would be a "perfect bonding experience" with his girls turned very sour, Thornton wrote. He said one of Klein's daughter's vowed never to talk to him again if he didn't take her to the concert.

That "overwhelmed" Klein, Thornton wrote. So he said, the next day, while driving to the 7-Eleven to buy lottery tickets, Klein "came up with a very bad idea."

"He hoped that [the bomb threat] would cause them to cancel the concert and he could tell his daughters that they should not be upset with him because the concert was canceled anyway," according to Thornton.

As it turned out, Klein's scheme — and especially his subsequent arrest — didn't make things better.

"Now," Thornton wrote, "his daughters are more upset with him."
