Yale grad student shot to death in what investigators feared was a perfect murder

On February 6, 2021, Kevin Jianga 26-year-old Yale graduate student and former member of the National Guard, spent the day with Zion Perry, his fiancée, who was also a graduate student there. The couple went hiking and ice fishing, followed by dinner at her home in New Haven’s affluent East Rock neighborhood. Police say that around 8:30 p.m., Jiang left his apartment and headed in his Prius toward his house, where he lived with his mother.

He barely made it two blocks before his car was struck from behind by a dark SUV in what appeared to be a minor fender bender. Police believe he got out of his car, probably to check on the other driver and exchange information. Instead, the other motorist shot Jiang eight times – with several bullets fired so close to his head that the exploding gunpowder left burn marks on his face.

David Zaweski, the lead detective on Jiang’s murder, spoke with “48 Hours” correspondent Anne-Marie Green for “The Ivy League Murder.” An encore of the show airs on Paramount+.

Zaweski said a witness told investigators she heard the small fender bender, looked out the window, heard gunshots and saw muzzle flashes from a weapon. And another witness added that not only did she hear the gunshots, but she saw the shooter – dressed all in black – standing over his fallen victim, continuing to fire bullets at him after he fell. Detectives then recovered chilling surveillance video that virtually captured Kevin’s last moments alive, confirming the witness’s accounts.

But what makes the mystery even greater is the fact that the eight spent shell casings found near Jiang were .45-caliber bullets – and they were similar to the .45-caliber shell casings found at the scene of four recent shootings in the area.

Police say a gunman fired .45-caliber bullets at four homes in recent months. In these cases, no one was injured. Investigators interviewed the owners but were unable to establish any connection between them.

On the surface, Jiang’s murder had all the hallmarks of a violent case of road rage. But Zaweski and his colleague Steven Cunningham soon began to wonder if there was more to it.

“It seems a little more personal,” Zaweski told Green. “When someone is lying on the ground and not moving, what would cause someone to continue shooting?”

Cunningham questioned the car crash. “Was it deliberate to remove him from the vehicle? Maybe something that was planned? he said.

“And if he had been specifically targeted,” Zaweski continued, “what could have happened in his life to cause someone to do that?

It was a logical line of investigation to follow, but after breaking the tragic news to Jiang’s mother and his fiancée, investigators say the portrait that emerged of Kevin was that of a gifted young man who could have no enemy in the world. He lived with and cared for his mother, whom he had brought from Seattle to live with him. He volunteered to work with the homeless, was deeply religious, and was a former lieutenant in the U.S. National Guard. Just a week earlier, he had proposed to Perry, which she posted on Facebook, virtually on the anniversary of their meeting at a Christian retreat.

Pastor Gregory Hendrickson summed up the young, newly engaged couple for Green. “They clearly shared a lot in common,” he began. “They both loved nature. Zion was a scientist who studied molecular biophysics and biochemistry…he was in the School of the Environment. They were both bright, hard-working students,” he said, “and yet they didn’t feel like their accomplishments were what defined them on the deepest level.”

Zaweski and Cunningham knew they faced a daunting investigation. Jiang’s murder could simply have been another random shooting carried out by the mysterious .45 caliber shooter. Whoever the shooter was, he was still at large.

“The suspect was there,” Zaweski said. “He wasn’t identified. We didn’t know where he was going…and we didn’t know what he would do next.”

With few leads to follow and a vague image of a dark SUV from surveillance footage at the scene, they knew they’d probably need a break. And they got one the next day when they received an urgent call from Sgt. Jeffrey Mills of the nearby North Haven Police Department. He gave them surprising information about two different 911 calls.

The first occurred about half an hour after Jiang’s murder. A motorist had become stranded on a desolate, snow-covered railroad track outside a scrap yard that he had accidentally entered, he said, while searching for a nearby highway entrance. The motorist, Qinxuan stovewas a native of Malden, Massachusetts. His record was clean and he was calm with an excuse that Mills had heard before from other people lost near this scrap yard. So he helped Pan get a tow and a nearby hotel room. At the time, Mills was unaware there had been a murder in New Haven.

But about 15 hours later, at 11 a.m. on Feb. 7, Mills responded to another 911 call at an Arby’s, where employees had found a bag containing a pistol and a box of .45-caliber bullets. The Arby’s was right next to the Best Western hotel where Pan had been taken. And at that moment, he knew that Kevin Jiang had been murdered by someone driving a dark SUV similar to Pan’s. That’s when he turned to New Haven Homicide.

It turned out that Pan had checked into the hotel but never stayed there. And when Zaweski sent detectives to Malden, where Pan went to the Massachusetts Institute of Technology (MIT) and lived with his parents, no one was home.

Zaweski turned to his computer in search of Pan, hoping to find a connection to Jiang. “We will use Facebook as a tool to try to get information about an individual that he is friends with,” Zaweski explained. But there seemed to be no connection with Jiang.

“And so you go through the list of names,” Green says, “Nothing, nothing, nothing, and then you’re like ‘whoa’.”

“That’s our connection,” Zaweski responds. That connection was Zion Perry, who was on Pan’s friends list. She and Pan had met in a Christian group when Perry was a student at MIT. And even though Perry barely knew Pan and hadn’t communicated with him since she left MIT and moved to New Haven to study at Yale, homicide detectives thought they had more than a break. They had a potential suspect missing from his home. And a possible motive: an obsession with Perry.

“It seemed like there was a secret Pan obsession going on behind the scenes that Kevin wasn’t aware of, and that Zion wasn’t aware of,” Zaweski said. After all, Jiang’s murder happened just a week after Perry posted their engagement on Facebook, along with previous photos of them as a couple.

Investigators believe Pan was also responsible for the four .45 caliber shootings and that the shootings were part of a premeditated plan. They speculated that these shots were carried out to mislead them when Jiang was eventually killed, to make them believe that his death was just another random incident.

“He planned it, Cunningham said. “And he knew we would look at these other things.”

“This was not a random incident,” Zaweski added. “He was targeted.”

Now their homicide investigation and massive manhunt for their brilliant, tech-savvy MIT fugitive has begun. U.S. Marshals joined the case and learned that Pan’s family had access to millions of dollars in assets. Pan was missing and they feared he might try to flee the country. The pressure was high.

“It became very high profile so quickly,” U.S. Marshal Joe Galvan told “48 Hours.” “It was just heightened.”

The marshals galvanized their vast resources to find Pan. They noticed that Pan’s parents had withdrawn large sums of money and had taken a long trip south with their son right after the murder. When the parents were arrested in Georgia, they were in the car, but their son was not there. They said he just got out of the car and walked away, and they didn’t know where he went. Investigators were skeptical.

“They would go to the ends of the earth to help support him and hide him,” said Matthew Duffy, supervisor of the U.S. Marshals’ fugitive task force in Connecticut. The marshals focused on the parents to find Pan. They knew finding him would take patience as they used all their surveillance techniques to find the family.

The weeks passed, but their patience finally paid off. Pan’s mother ultimately made a mistake that led the marshals directly to her son. She made a phone call from a hotel using an employee’s phone. Investigators spoke to the clerk and were able to track that call, leading them to Pan’s location at a boarding house in Alabama.

“They went with a small army,” Duffy said. “About 20 guys…he just came out and said, ‘I’m the one you’re looking for.'”

At the time of his arrestPan had about $20,000 in cash, several communications devices and his father’s passport on him. He was charge with Jiang’s murder, accepted a plea deal and was sentenced in April 2024 to 35 years in prison.

Pan’s parents were never charged with anything. “48 Hours” contacted the Pans, but they did not respond to our request for comment.

Investigators believe that if Pan had not gotten stuck on the train tracks that fateful February night, Jiang’s murder may never have been solved.

“Could he have gotten away with murder?” » Green asked Zaweski.

“He very well could have,” Zaweski replied. “If he hadn’t been caught by these traces… it would have been very difficult.”

Although investigators, friends and family were relieved that Pan was arrested and brought to justice, Jiang’s mother spoke at Pan’s sentencing to say that she felt 35 years in prison was too short a sentence for the man who killed her only son.

Perry agreed. “I wanted to address Pan specifically,” she said during the sentencing. “Although your punishment is far less than you deserve…there is also mercy. May God have mercy on you. And may He have mercy on all of us.”

Even four years after Jiang’s death, friends wonder what Kevin, a man of deep faith, might have thought of his killer.

“Do you think Kevin would have forgiven Pan?” Green asked Jamila Ayeh and Nasya Hubbard, who served with Jiang in the military.

“Yes, I do,” Hubbard said. Ayeh added: “Without a doubt.”
