A Colorado grand jury voted to indict the parents of slain child beauty queen JonBenet Ramsey more than 13 years ago, but prosecutors reportedly refused to go forward on the case, according to the Boulder Daily Camera newspaper.

The grand jury voted in 1999 to indict John and Patsy Ramsey on charges of child abuse resulting in death, three years after their 6-year-old daughter was bludgeoned and strangled in the basement of her family's house on Christmas Day.

But former Boulder County District Attorney Alex Hunter declined to sign the indictment, believing he could not prove the case beyond a reasonable doubt, the Daily Camera reported.

"I and my prosecution task force believe we do not have sufficient evidence to warrant the filing of charges against anyone who has been investigated at this time," Hunter told reporters in October 1999.

"Child abuse resulting in death" is a Class II felony punishable by up to 48 years in prison, according to the Daily Camera.

"We didn't know who did what," a juror told the Daily Camera on the condition of anonymity. "[B]ut we feel the adults in the house may have done something that they certainly could have prevented, or they could have helped her, and they didn't."

Hunter, who left his post in 2008 after 28 years as district attorney, declined to discuss the grand jury's decision, according to the Daily Camera.

But in a 2001 interview with NBC News, Hunter said he had no regrets about his decision not to charge anyone.

"I have enough people that I respect that have said to me, 'You know, you made a tough call, you made a call the public didn't like. But you were true to the law, you were a good prosecutor, and that's plenty for me.'"

Lin Wood, John Ramsey's attorney, backed up Hunter's decision in a statement to NBC News.

"The DNA tests performed after the time of the Boulder grand jury not only prove the Ramseys to be innocent and the grand jury wrong, they also make D.A. Alex Hunter a hero who wisely avoided the miscarriage of justice," Wood said.

Patsy Ramsey died of ovarian cancer in 2006. The couple and their older son, Burke Ramsey, were exonerated in the case in July 2008, even though they were never formally charged in connection with JonBenet's death.

"To the extent that we may have contributed in any way to the public perception that you might have been involved in this crime, I am deeply sorry," former Boulder County District Attorney Marcy Lacy wrote in a letter to John Ramsey in 2008. "No innocent person should have to endure such an extensive trial in the court of public opinion."

Updated at 1:45 p.m. ET: A Utah woman got a startlingly rude awakening at her hillside home over the weekend: a boulder in her bedroom at 3 a.m.

Wanda Denhalter, 63, was home alone on Saturday when the enormous rock crashed into her room, breaking her jaw and sternum, and leaving a huge gash on her leg, The Salt Lake City Tribune reported. Her husband Scot, who was out of town for the night visiting his son, told The Tribune he estimated the boulder that he returned home to was about 12 feet long, 9 feet high, and 9 feet wide.

"I guess she heard the rumbling as it came down the hill and woke up," Scot Denhalter, 62, told The Tribune. "She rolled away from the oncoming noise to my side of the bed. If she had decided to swing her legs over the side of the bed and get up to investigate, it would have killed her."

Somehow, despite her injuries, Wanda Denhalter managed to get help.

"She stumbled around, probably in shock. She found her phone and called 911,” Denhalter told St. George local media source Spectrum.com. "I feel a bit guilty I wasn't there."

The couple just moved into the rental home in St. George in mid-December, local reports said. No one else was hurt when the boulder came loose. It's unclear what caused it to come rolling down the hill in the first place, but Scot Denhalter said a neighbor told him water appeared to be draining from a home on top of the ridge.

“It might have been a pipe that froze and broke," he told Spectrum.com. "It’s been kind of leaking into the fissures and cracks of the ridge, and I think last night when the water froze, it snapped and down it came.”

While police were not able to pinpoint exactly what sent the boulder rolling down the hill, St. George city spokesman Sgt. Marc Mortensen said Tuesday that no further investigation was planned on the incident, which he described as a "natural occurrence." 

"The boulder in the hillside was in its natural state. It evidently broke loose or the soil around it somehow came loose," he said. "In our county and in our city, we have hillsides all over the place. We're very hilly. So this type of occurrence, while not common, it does happen from time to time."

Usually, though, people aren't injured because the boulders are significantly smaller. Police are not concerned about more boulders falling in the area, he added.

Wanda Denhalter has been released from the hospital and is recovering from her injuries, he said.

"What a wake-up call!" Mortensen said of her 3 a.m. ordeal.

Scot Denhalter said he was relieved his wife was alright.

“When we first moved in, my wife said, ‘Don’t you love the backyard?,’ and I did because of the position of the ridge,” he told Spectrum.com. “[But] I said you could have a big boulder snap and come down and come right through the house, but she said that would never happen.”

“I’m greatly relieved she’s OK,” he said.

St. George is a desert community in the southwest corner of Utah, on the border of Arizona. 

LAFAYETTE, Colo. – Boulder County sheriff’s deputies say a man and a woman were seriously injured after a package left at their home exploded Saturday afternoon.

Their conditions were not immediately known, The Denver Post reported.

Police say they believe there may be another package in the car and were searching it with a bomb robot.

Neighbor Tim Walker told the Post that the woman had picked up two packages left at her doorstep and was loading them into a silver Volvo, parked outside the home, when one blast occurred.

Deputies evacuated several residences from the neighborhood by using ladders to help people climb over fences, the Denver newspaper reported.
