Police and FBI agents looked at Gregerson for some time. They were unable to remove him from their list of people that they were investigating in connection with Destiny's disappearance.

"We would never, ever cross anybody off the list until we were fully satisfied that individual could explain where they were," said Tim Fuhrman, the special agent-in-charge of the FBI's Salt Lake City office.

Gregerson met with an FBI agent July 24. According to the criminal charges, Gregerson told the federal agent what happened.

"There was an interview, and he confessed," Stott said.

Gregerson's estranged wife, Catherine, has said her husband took a polygraph test Monday. Later that day, he was arrested, and Destiny's body was found.

Gregerson remains in the Salt Lake County Jail on $5 million bail.

The details of Destiny's death horrified her family and friends. Many were outraged that Gregerson participated in searches and vigils for Destiny.

"I'm devastated," family friend Jeannie Hill said.

Speaking to reporters at Liberty Park, she wore a black armband with Destiny's name and a heart symbol to memorialize the little girl.

"I can't even say his name," Hill said of Gregerson. "I feel personally that he does not deserve a Christian name."

Death penalty case?

Gregerson is charged with aggravated murder, a capital offense. However, prosecutors have not decided if they will seek the death penalty against him.

"Right now we are focused only on the conviction," Stott said.

Destiny's family and friends offered mixed opinions about whether they wished for Gregerson to die, if he is convicted.

"It makes me very angry," said Donna Archuleta, the "street mom" of the Norton family. "I'm glad they're going for the death penalty."

Outside the Norton home, people continued to bring flowers, stuffed animals, balloons and condolence cards. They placed them up against a pair of trees in front of the home. A cardboard butterfly hung from a branch. A child had written on it "Fly High Destiny!"

Dozens of candles continued to burn around a makeshift memorial to the little girl with a bubbly smile full of silver teeth.

Jody Emery, another of Destiny's uncles, said he wasn't sure if death would be good for someone like Gregerson.

"I almost think the death penalty would be too convenient of a punishment," he told the Deseret Morning News.

Destiny's parents have not offered an opinion on whether prosecutors should ask for the death penalty. They met with prosecutors Thursday morning shortly before the charges were announced. Stott said they did not discuss the death penalty.
