'How do I spend the rest of my life without my daughter?'

For more than four months, Ronggao Zhang has walked to his missing daughter's apartment almost every day. At first, he stood outside, hoping she would show up one afternoon. But even after he was told she'd been kidnapped and was presumed dead, he's continued his routine.

"It brings peace and comfort to my heart," Zhang explained in Mandarin, through a translator.

His daughter, Yingying Zhang (ying ying zahng), a 26-year-old visiting scholar at the University of Illinois at Urbana-Champaign, disappeared June 9 on her way to sign an apartment lease. A former graduate student has been charged with kidnapping and killing her. Zhang's body has not been found.

A few days ago, Zhang's father made a final visit to the Orchard Downs apartments with his wife, 24-year-old son and daughter's boyfriend as they prepared to return to China. They arrived here after Zhang vanished, hopeful in the beginning that she'd be found alive. After authorities relayed the grim news, they decided to stay until her remains were found so they could take her home for a proper burial, in accordance with Chinese customs.

Now they plan to leave Sunday, reluctantly, without her. Zhang's mother is in fragile health — she broke down at the start of a recent court hearing — and there's no way of knowing when this cruel mystery will be solved. Each day they wait, in agony.

"We don't know where she is, and I don't know how to spend the rest of my life without my daughter," said Lifeng Ye, Zhang's mother, her face tear-stained and voice trembling as she spoke through a translator. "I can't really sleep well at night. ... I often dream of my daughter, and she's right there with me. I want to ask the mother of the suspect, please talk to her son and ask him what he did to my daughter. Where is she now? I want to know the answer."

Authorities have not said how Zhang died. Brendt Christensen, 28, was charged in July with abduction and then last month accused in a superseding indictment of kidnapping resulting in death "in an especially heinous, cruel or depraved manner, in that it involved torture or serious physical abuse to the victim." That carries the possibility of the death penalty. Christensen's lawyer declined comment.

Federal prosecutors claim that Zhang, who arrived on campus in April, had missed a bus and worried she was late to sign an apartment lease when Christensen lured her into his car. Surveillance video showed her getting into the front seat of a black Saturn Astra the FBI alleges was cleaned in a way to conceal evidence.

Audio surveillance captured Christensen talking about how he abducted Zhang and brought her back to his apartment, where she "fought and resisted" while he held her against her will, according to prosecutors. They contend he also talked about who makes an "ideal victim," but prosecutors would not identify whom Christensen was speaking with or the source of those conversations.

A federal complaint disclosed that Christensen used his phone in April to visit a fetish networking site online, viewing threads titled "perfect abduction fantasy" and "planning a kidnapping." Christensen, who earlier this year earned a master's degree in physics, appeared at a campus vigil for Zhang in June before he was arrested.

Zhang's disappearance has rippled far beyond this quiet central Illinois community, generating headlines and discussion in Chinese newspapers and social media sites about the American justice system, the capabilities of law enforcement, and whether scholars who study in the U.S. are safe.

Some 5,600 Chinese students attend the university here — more than any other college in the nation. The Urbana-Champaign area typically has no more than a few homicides a year.

Studying in America was a longtime dream for Zhang and "she loved her stay here," said her boyfriend, Xiaolin Hou, who was in touch with her every day via WeChat, a popular social network in China.

She chose Illinois for its highly regarded agriculture program. Zhang had been doing research on crop photosynthesis. She was to begin her doctoral work in September after having earned a graduate degree in environmental engineering from the prestigious Peking University Shenzhen Graduate School.

"She was very tough, strong, never afraid of hard work," her mother said, recalling how she was at the top of her class ever since she was a little girl. Zhang was a calming influence, too, when her parents expressed concern about her safety in America. "She always told me, 'Mom, don't worry about me. There are Chinese here, Americans here. But everyone is very nice here.'"

Zhang was a devoted daughter. At the same time every Saturday, she'd call her parents in Nanping, China. As a graduate research student, she used her meager savings to buy her family a cellphone, an air conditioner and a microwave oven. She planned to become a university professor and help support her father, a factory worker, and mother, a homemaker.

"She never hesitated, even for a moment, when others needed help," said her boyfriend, who put his doctoral studies on hold to join Zhang's family here. He said her selflessness was what attracted him to Zhang when they met in their first year in college. She also knew how to have fun, playing guitar and singing lead in a band called "Cute Horse."

Hou and family members have met with the FBI, police and prosecutors, but they're frustrated by the slow pace of justice, said Zhidong Wang, a Chicago lawyer who has been helping them. He said he's explained that even though authorities have a suspect, Christensen's constitutional rights protect him from being forced to reveal anything that would hurt his defense.

Christensen's lawyers recently sought a delay in the trial until next October, saying they needed to check into several purported sightings of Zhang and reports of suspicious people around her apartment before she disappeared.

Zhang's father said the loss of his daughter has warped his sense of time: "Every day is like a year."

Hou, Zhang's boyfriend of eight years, has struggled, too. Though they didn't have marriage plans, he said, "In my heart, she is my wife for all time."

When authorities provided scanned pages of Zhang's diary to the family, Hou said it hurt too much to read them thoroughly. She wrote regularly of long-term and short-term goals and meticulously detailed how she organized her day — 20 minutes for breakfast, 20 minutes for jogging.

On June 1, her last entry, Zhang was a bit more philosophical.

"Life," she wrote, "is too short to be ordinary."

Hou said it will be hard to leave and wait from thousands of miles away to bring Zhang home.

"We don't know how much longer this journey is going to be," he said. "We just feel hopeless."

The Michigan synagogue that came under attack this week when an armed man drove his car into the building had for months been strengthening its security apparatus by hiring a seasoned police lieutenant as its security director and holding active shooter training.

That beefed up security, which came in response to rising antisemitism and other attacks at places of worship, is being credited with saving lives in an event that ended with only the attacker dying.

An armed private security guard shot back at the attacker after he opened fire through his windshield in a hallway inside the building. When the car barreled in, there were 140 students inside in an early childhood learning center. All were unscathed.

The car’s engine caught fire, and the gunman, Ayman Mohammad Ghazali, a Lebanese-born U.S. citizen, eventually used his own weapon to fatally shoot himself, according to Jennifer Runyan, the special agent in charge of the FBI’s Detroit field office.

“If they had not done their job almost perfectly we would be talking about an immense tragedy here today with children gone,” U.S. Sen. Elissa Slotkin said of the building's security.

Michigan Gov. Gretchen Whitmer added: “These heroes threw themselves in harm’s way, engaging a suspect.”

One of Temple Israel's rabbis said “it was only a miracle” that none of its members were hurt.

“Unfortunately the entire Jewish community, no matter where we are in the world, we have to plan for things like this,” Temple Israel Rabbi Jennifer Kaluzny told CNN.

The effort to bolster security at Temple Israel, outside Detroit, came as many houses of worship have undergone similar efforts, with leaders working to fortify facilities in the wake of deadly attacks. Synagogues around the world have increased protections after the U.S. and Israel launched a war with Iran.

The synagogue last June hired a former police lieutenant, Danny Phillips, to lead its in-house armed security guards as the head of security, with the temple saying it was taking a proactive step “in response to the evolving realities facing Jewish communities.”

Phillips served in law enforcement for almost three decades, including more than 20 years as his department's advanced firearm instructor, according to the website of a college where he teaches a police academy course on responding to active assailants.

And in January, Temple Israel's staff and clergy participated in an active shooter prevention and preparedness training led by an FBI official, according to the synagogue's social media accounts.

Oakland County Sheriff Mike Bouchard said on Thursday that he had contacted the head of security for the temple just two days before the attack. He credited the thorough preparation ahead of the attack as the reason that there weren’t casualties.

Ron Amann, a member of the safety team at CrossPointe Community Church in Wayne, Michigan, is still recovering after being shot in the leg by a man who tried to attack the Christian church last June. The gunman was killed by another team member before he could enter a Sunday service.

Amann, who was armed, said he passed his grandson to his wife when he heard a woman yell, “There’s a man with a gun.”

“When you sign up for the safety team you have to be willing to stand up and fight, bluntly, rather than run the other direction,” said Amann, 64, who has a metal rod in his lower right leg.

“My alertness is just at a higher level than it ever was before,” he said. “The events at the synagogue just keep bringing it back to the forefront. I’m certainly saddened by all that.”

CrossPointe church is 30 miles (48.2 kilometers) from the synagogue. But Pastor Bobby Kelly said he and his staff sheltered in place Thursday when they heard about the attack. Police even drove around the church.

“When you hear of something happening,” Kelly said, “you don’t know where it’s going to happen next.”
