People were turned away from the funeral for Judge John Roll after the church filled to capacity.

Traffic backed up for miles along North Shannon Road as people made their way to the funeral of Judge John Roll this morning.

Security was tight and the U.S. Marshals Service set up two checkpoints and screened all vehicles entering St. Elizabeth Ann Seton Catholic Church.

Dozens of dignitaries including former Vice President Dan Quayle  attended.

Adam Goldberg, a spokesman for the fire department and the event, says Quayle was to present a handwritten message from former President George H.W. Bush, who appointed U.S. District Judge John Roll to the bench.

Coach buses full of judges pulled into the church parking lot Friday morning.

Across the street, people lined the road to pay tribute to Roll, one of six people killed in Saturday’s shooting.

Bagpipes played as people filed into the church.

Jay Stanforth, 54, walked along the line of spectators and handed out red roses.

“We don’t want to be in the funeral but want the family to know that positive energy is surrounding them,” the retired teacher said.

At the funeral of 9-year-old Christina-Taylor Green Thursday, Stanforth said someone handed him a rose and he decided to do the same today.

Packing two camping chairs and a cup of coffee, Jason Terpstra, 34, a heating and cooling service technician, said he knew Roll when he was a child and used to call him “Uncle John.”

Terpstra said he showed up on this chilly morning, “Just to be here. Just to remember”

About 16 people wearing large angel wings arrived shortly after 9 a.m. and stood along the road until the funeral Mass began at 10 a.m.
