The Murder of Yancy Noll
On August 31, 2012, around 7:10 p.m., Yancy Noll was driving his Subaru Forester home from work when he stopped at a red light at the intersection of 15th Avenue Northeast and Northeast 75th Street in Seattle’s Roosevelt neighborhood. A silver BMW Z4 pulled up next to him on the passenger side and opened fire. Five shots were fired in rapid succession, four of which hit Noll in the head and killed him instantly. The fifth bullet went into a nearby home. The shooter then sped away into oncoming traffic.

Noll was 42 years old and worked as a wine steward at a local grocery store. He was described by his friends and family as a happy-go-lucky, outdoorsy, and kind-hearted person who loved wine and his dog Lola. He had no enemies or conflicts with anyone.
The shooting shocked and terrified the community, as it seemed to be a random and senseless act of violence. The police launched a massive manhunt for the killer, who was seen by several witnesses and captured by surveillance cameras. They released a sketch of the suspect and offered a $30,000 reward for information leading to his arrest.
The Arrest of Dinh Bowman
Two weeks after the murder, an anonymous tipster called the police and identified the shooter as Dinh Bowman, a 29-year-old robotics engineer who lived ten blocks away from the crime scene. The tipster said he recognized Bowman from the sketch and knew he owned a silver BMW Z4.
The police tracked down Bowman’s address and found his car parked outside his house. They noticed that the car had been modified: the passenger side window had been replaced, the tires had been changed, and the rims had been spray-painted black. They also found shards of glass in the door well that matched the window that was shattered by the bullets.

The police arrested Bowman on September 21, 2012, and searched his house. They discovered a hidden room behind a bookcase that contained guns, ammunition, silencers, explosives, fake IDs, disguises, manuals on how to kill people, and a map of Seattle with red dots marking potential shooting locations. They also found evidence that Bowman had researched Noll online before killing him.
Bowman was charged with first-degree murder with a firearm enhancement. He pleaded not guilty and claimed he acted in self-defense after Noll attacked him on the road for cutting him off. He said he fired his gun through the window to scare Noll away.
Wedding, Wife & Children
Dinh Bowman’s wife was Jennifer Bowman (née Palm), a dentist who married him in 2008 after meeting him at an education seminar. They lived together in Seattle and had a collection of firearms and ammunition in their home. Jennifer was with Dinh when he replaced his car window and tires after the shooting of Yancy Noll.
She was questioned by the police but was never charged with any crime. She also did not attend any of Dinh’s court hearings, but they kept in touch through jailhouse phone calls, where they called each other “Bunny” and “Snuggles” and used baby talk.

Jennifer filed for divorce from Dinh in 2015, shortly after he was sentenced to 29 years in prison. She changed her name to Jennifer Palm and moved to California, where she continues to work as a dentist. As far as we know, Dinh and Jennifer did not have any kids.
The Trial
Bowman’s trial began on November 24, 2014. The prosecution argued that Bowman was a cold-blooded killer who planned and executed the murder of Noll for no reason other than thrill-seeking. They presented witnesses who testified that they saw Bowman shoot Noll without any provocation or interaction. They also showed video footage that contradicted Bowman’s claim that he cut off Noll on the freeway. They said Bowman was obsessed with guns and violence and wanted to test his skills as a marksman.

The defense argued that Bowman was acting in self-defense after Noll threatened him with a wine bottle on the road. They said Bowman was afraid for his life and fired his gun to stop Noll from attacking him. They also said Bowman was a genius and a successful engineer who had no motive to kill Noll. They said Bowman was a victim of mistaken identity and false accusations.
The jury deliberated for three days and found Bowman guilty of first-degree murder with a firearm enhancement on December 11, 2014. He faced a minimum of 25 years and a maximum of life in prison.
The Sentence
On January 9, 2015, Bowman was sentenced to 29 years in prison by Judge William Downing. The judge said Bowman showed no remorse or empathy for his actions and called him a “sociopath” and a “danger to society”. He also said Bowman’s claim of self-defense was “preposterous” and “insulting”.
Bowman’s wife, Jennifer, who stood by him throughout the trial, spoke in his defense and asked for leniency. She said Bowman was a loving husband and a good person who made a terrible mistake. She also said he was suffering from mental illness and needed treatment.

Noll’s family and friends also spoke at the sentencing and expressed their grief and anger over his death. They said Noll was a wonderful person who did not deserve to die. They also said Bowman was a coward and a monster who should never be released.
Bowman did not speak at the sentencing. He showed no emotion as he was led away in handcuffs.
