Vanished: Two Coeds, Two Horrifying Mysteries

It's one of the most exciting times of a young adult's life: starting college and moving out of mom and dad's nest to a place of one's own. But too often for young people, particularly young women, that newfound independence is coupled with dangerous vulnerability.

Figures gathered by the FBI say there are more than 21,500 active missing person cases involving people between the ages of 18 and 29. Brooke Wilberger and Maura Murray are two young women included in that tragic statistic. Their stories powerfully illustrate how communities can rally and families' faith and hope get tested when a loved one has vanished.

Brooke and Maura's stories are similar in many ways. Both were smart, beautiful young women with loving friends and family. They were active in their communities. They had boyfriends who adored them. They were on the verge of very bright futures. Then they disappeared.

Community Rallies to Search for Brooke

The story of Brooke Wilberger's disappearance begins on the afternoon of May 24, 2004. The 19-year-old Brigham Young University student was home in Oregon visiting her family, and helping out her sister and brother-in-law at an apartment complex they manage in the town of Corvallis.

Corvallis is a picturesque Oregon city of about 54,000 people. It's a place most people would consider ideal for raising a family. But even idyllic places can be visited by crime. "The city of Corvallis is really safe, but we're also in the real world," said Lt. Ron Noble of the Corvallis Police Department.

Brooke was in the parking lot of the complex cleaning lamp posts. When Brooke didn't show up for lunch, her sister, Stephani Hansen, began to worry.

Brooke's car keys and purse were in their apartment. Her car was in the lot. Her flip-flops were found, but Brooke was gone.

"I got very nervous ... we had exhausted every possibility, we had searched all the apartments that she could possibly be working in. We looked everywhere -- then we called the police," her sister recalled.

Noble remembers receiving the call about the case. "Normally, we would wait. Because adults can come and go as they please and we would normally wait to see if she showed up maybe the next day," he said. But police officials agreed with Brooke's sister; they sensed Brooke was not the sort of young woman to disappear on her own.

"It was amazing to us that they acted that fast, and I think one of the reasons was when they immediately did a quick check, [they saw] Brooke was a great kid," said her mom, Cammy Wilberger.

As their search began, police eliminated one usual suspect in similar cases -- the boyfriend.

The man in Brooke's life, Justin Blake, who had dated Brooke since high school, was doing Morman missionary work in Venezuela.

Marriage was on the horizon for the couple, he said. "I was gonna propose. We just both sort of knew what was gonna happen when I got back from my mission," he said.

His parents called him in Venezuela to deliver the news that would shatter those plans. "They just started crying when they heard my voice and so I just started crying," he recalled.

In Corvallis, a community-wide search effort had been organized with unusual speed.

"The community of Corvallis was wonderful. That first night they had hundreds of people helping search," Brooke's mother recalled. "Our church organized it, but everyone in the community filled in," she said.

"There were a lot of areas to search and some of it very, very heavy with heavy vegetation. In fact, I remember going home at 1 o'clock in the morning and there were still 300 people doing concentric circles from where Brooke was last seen," said Noble.

The first night ended with no sign of Brooke.

In the morning, the townsfolk of Corvallis would awake to a shock of another sort - the largest gathering of media the town had ever seen.

"We had to operate on a whole different paradigm for this investigation, because we didn't have anything to go on. So we needed the media to stay here to talk about the case so people would call in tips," Noble said. Despite the authorities' quick response, the community support and national media coverage, it was years before there was a real break in the case.

Was Maura Murray Abducted, or Did She Run Away?

Brooke was 19 when she disappeared and police began investigating immediately, but that's not always the case. With missing persons over the age of 18, police are very likely to wait a few days because, authorities tell us, adults have a right to disappear.

Authorities followed that procedure in the case of 22-year-old Maura Murray, who went missing Feb. 9, 2004, after she was in a minor car accident in New Hampshire.

Authorities believed she may have wanted to disappear, but her family and friends were certain her disappearance was not by her own choice.

Like Brooke, Maura was an excellent student. Before attending nursing school at the University of Massachusetts, she had attended the U.S. Military Academy at West Point, where she met a young man, Bill Rausch, and fell in love. After Rausch graduated West Point, he was stationed in Oklahoma as Maura finished school in Massachusetts. But that distance only seemed to deepen their commitment to each other.

Shocked and upset, Rausch called his parents after learning that Maura had gone missing. "I answered the phone, and I heard panic in his voice," his mom, Sharon Rausch, said.

But there were immediate questions surrounding Maura's disappearance. For reasons she apparently shared with no one, the 22-year-old left her dorm in Massachusetts and drove to New Hampshire.

Reporter Joe McGee, covered the story for The Patriot Ledger in Quincy, Mass. "At a hairpin turn, she went off the road. Her car hit a tree. At that point, a person came along who was driving a bus. It was a neighbor. He asked her if she needed help, she refused. About 10 minutes later, police showed up to the scene and Maura Murray was gone," McGee said.

News of that night's events reached Maura's father, Fred Murray, when police called at 4 p.m. the next day.

"My immediate reaction when I found out that my daughter was missing was right at the edge of panic. You found her car? She was in an accident? She's not there? Where is she? Where is the search now? You know, how far have you looked now? And and as it turns out, there was no search," he said.

In this case, the initial conclusion at the scene was that Maura had probably left on her own free will. But a day and a half later, with still no sign of her, authorities investigated further.

"They brought out helicopters, ground crews to search the area and dogs. But two things stood out. No. 1, there were no footprints left in the snow. And No. 2, dogs lost her scent about 100 yards away from the scene," The Patriot Ledger's McGee said.

Police reported that there were no signs of struggle at the scene, and their conclusion seemed to be that she had run away.

Maura's boyfriend doesn't believe the woman he planned to marry would simply run away. He got an emergency leave from the Army to search for Maura. "I kept hearing, well, she's an adult, and I was the only one out there walking up and down the street, looking over snowbanks, trying to find footprints, trying to find some sign of her," he said.

Rausch's parents were devastated by Murray's disappearance. "For all of us that love Maura, life is like a nightmare. I can honestly say that I can't imagine loving anyone that's not my child anymore than I love Maura," Sharon Rausch said.

Wilberger Family Offers Support, Maura's Father Presses On

Three months later, as the fact of Maura's disappearance lingered without answers, her family saw reports of another missing young woman -- Brooke Wilberger.

Sharon Rausch saw how Wilberger's community rallied around the family and joined the search, and she wanted similar action for her son's missing girlfriend.

The two families began to share e-mails. "We talked about our faith in God and that we would not give up hope and that Brooke and Maura were in God's hands," Rausch said.

Maura's father was angered by the lack of progress on the case, and complained that authorities had made up their mind that his daughter had run away and were not devoting enough attention to her disappearance.

"I don't agree with some of his observations, but I understand certainly his frustration in not knowing what happened to his daughter," said Lt. John Scarinza, commander of the New Hampshire State Police Troop F .

"It's clear to us that it was her intention to at least get away for a certain amount of time," Scarinza said, noting that his department investigates cases in which people come to the New Hampshire mountains to get away from their problems several times a year, "sometimes with the intention of harming themselves."

But that scenario still makes no sense to Maura's father. "She didn't just wander into the woods to try to commit suicide. She has everything to live for. She was going to graduate in June into a nursing career. She was about to get engaged," he said.

However, Maura's family and closest friends have no idea what drew her to that lonely New Hampshire road. And they were surprised at some of the things police and reporters discovered.

"She took a lot of belongings and didn't tell anybody where she was going other than e-mails she sent to a professor saying that there had been a death in the family and that she needed to leave unexpectedly. And then she headed north," said McGee.

Regardless of what brought Maura to that remote area, her father wants to know where she is now. Most weekends he travels from Massachusetts to the New Hampshire spot where Maura slid off the road and into a tree.

He has gone to the state capitol and met with the governor in a closed-door meeting, demanding answers about the investigation. His confrontations with the police and state officials, and his constant prowling around New Hampshire, raised speculation in some quarters that he was becoming kind of a nutty nuisance.

But Murray's relentless pursuit for answers caught the attention of Tom Shamshak, a former police chief and member of a group of private investigators who offer pro bono help in situations that capture their interest. In January they took on Maura Murray's case.

Shamshak and his colleagues looked at the case with a fresh set of eyes. Based on their investigation, Shamshak said, "It appears, just based on what I have reviewed with the other investigators from New Hampshire, Maine and Vermont that are part of the team, that this is something beyond a mere missing persons case. Something ominous could have happened here."
