Tyler Sorensen: What We Know About The Costco Employee Charged With Murdering A Coworker
Tyler Sorensen, a 22 year old former Costco employee from Renton, Washington, is facing a second-degree murder charge after prosecutors say he deliberately rammed his car into a coworker’s motorcycle outside a Costco warehouse in Issaquah, Washington, killing him. The coworker, 20 year old Jonathon Langdon, died at the scene on July 31, 2026. Court documents allege the collision followed a jealous outburst after Sorensen saw Langdon hug a female coworker he was reportedly infatuated with.
This article lays out what has been confirmed through court filings, police statements, and reporting from outlets that reviewed the charging documents, including KOMO News, PEOPLE, the New York Post, and the Issaquah Spotlight. Because this is an active criminal case and Sorensen has pleaded not guilty, the account below reflects allegations, not proven facts. A jury, not a headline, will ultimately decide guilt.

How The Crash Happened, According To Court Documents?
Sorensen and Langdon both worked at the same Costco location in Issaquah and finished their shifts on the evening of July 31. Investigators say the two, along with a third coworker named Samantha Peterson, crossed paths in the Costco parking lot before the fatal encounter. According to the probable cause affidavit reviewed by multiple outlets, Sorensen saw Langdon hug Peterson and reacted with anger, later texting friends that his “blood is boiling.”
Prosecutors allege Sorensen first revved his engine and drove close to Langdon and Peterson in the parking lot, narrowly missing them, before waiting roughly ten minutes for Langdon to leave on his motorcycle. Surveillance video obtained by investigators reportedly shows Sorensen’s gray sedan following Langdon’s motorcycle, swerving across lanes, and striking the rear of the bike.
The impact threw Langdon from the motorcycle into a metal signpost. Despite efforts from responding police and fire crews, he was pronounced dead at the scene. He had been wearing a helmet at the time of the crash, according to reporting citing the New York Post.
Note: Because charges are based on a probable cause affidavit and continuing investigation, some specifics, including the precise sequence of events and any physical evidence still under review, could be refined as the case moves through King County Superior Court.
What Sorensen Allegedly Told Police
According to the Issaquah Police Department and court records, Sorensen did not stop at the scene. Investigators say he drove home, pausing only once to check whether his car was still drivable. A Washington State Patrol trooper stopped and cited him for speeding on the way home, unaware at the time that he had just been involved in a fatal collision.
Sorensen’s father is said to have learned what happened once his son arrived home and brought him back to the crash scene roughly an hour later, at which point Sorensen made statements to officers that led to his arrest.
During questioning, Sorensen reportedly admitted to intentionally striking Langdon’s motorcycle “in an act of anger,” though he also told detectives he had only meant to “spook” Langdon and had not intended to kill him. One statement attributed to him in the charging documents reads, “It was stupid but I, I was, I meant to do it.” He also described the moments leading up to the crash as driven by panic and adrenaline after seeing Langdon with Peterson.
The Alleged Motive: A One-Sided Relationship
Prosecutors say the case centers on Sorensen’s belief that he and Samantha Peterson had a romantic relationship, a claim she denies. According to the charging document, Sorensen referred to Peterson as his “ex-girlfriend” and had what senior deputy prosecuting attorney Elaine S. Lee described in court as a possessive mindset toward her.
Peterson told investigators she and Sorensen were never in a dating relationship, that she considered him only a friend, and that she had repeatedly asked him for space after he crossed boundaries.
That distinction matters for the case, because prosecutors are using it to argue Sorensen’s anger toward Langdon was rooted in a delusion of ownership over Peterson rather than any real betrayal. Whether that framing holds up will likely become a central issue at trial.
For readers trying to understand why an alleged workplace friendship escalated into a fatal confrontation, this gap between how Sorensen described the relationship and how Peterson described it appears to be the crux of the prosecution’s theory of motive.

Charges Sorensen Is Facing
Sorensen was not charged with a single count. According to reporting on the charging documents, prosecutors filed three felony counts connected to the July 31 crash.
- Second-degree murder, the lead and most serious charge
- Second degree assault with a deadly weapon, related to the vehicle itself being used as the weapon
- Criminal attempt, reportedly tied to the earlier moment in the parking lot when Sorensen allegedly nearly struck Langdon and Peterson before the fatal pursuit
Washington law defines second degree murder as causing a death with intent to cause serious harm, or, in some circumstances, causing a death during certain other felony conduct, without the premeditation required for a first degree murder charge. Prosecutors do not need to prove Sorensen planned the killing, only that he acted with intent to cause substantial harm when he struck Langdon’s motorcycle.
Court Proceedings So Far
Sorensen was arraigned in King County Superior Court on Thursday, August 6, 2026, where he pleaded not guilty to the second-degree murder charge. A judge set his bail at $2 million and ordered him held at the King County Correctional Facility. As a condition of his release should he post bail, the court barred him from contacting Langdon’s family, Samantha Peterson, or any eyewitnesses connected to the case.
According to the Issaquah Spotlight, which reviewed King County court documents, Sorensen’s trial date has been scheduled for September 28, 2026. Before that, he is set to appear for a routine pre-trial conference on August 27, 2026. Pre-trial conferences of this kind are procedural hearings where attorneys and the judge address scheduling, evidence disclosure, and any pending motions rather than the substance of the case itself.

Who Was Jonathon Langdon?
Jonathon Langdon was 20 years old and worked alongside Sorensen and Peterson at the Costco location in Issaquah. Public reporting on the case has focused primarily on the circumstances of his death rather than a detailed personal profile, and no verified biographical details beyond his age, hometown of Issaquah, and employment at Costco have been confirmed through court documents or the outlets that have covered the case. He was riding his motorcycle home from work, wearing a helmet, when he was struck.
Costco’s Connection To The Case
It is important to be precise about Costco’s role here. Costco Wholesale is the employer that all three people involved, Sorensen, Langdon, and Peterson, worked for at the time of the incident, and the crash occurred near a Costco warehouse location in Issaquah. Costco itself is not a party to the criminal case and has not been accused of any wrongdoing.
Reporting from PEOPLE indicates the outlet reached out to Costco for comment following the charges, though no statement from the company has been widely reported as of this writing. Readers searching for information about “Costco employee treatment,” workplace culture, or how the company handles conduct issues among staff should understand that this case has not, based on available reporting, been tied to any broader claim about Costco’s policies or workplace practices.
Why This Case Is Getting National Attention
Workplace violence cases draw scrutiny for a simple reason: most people spend more waking hours with coworkers than with almost anyone else, and a case like this one raises uncomfortable questions about how quickly ordinary tension between colleagues can turn dangerous.
The surveillance footage cited in court filings, showing a vehicle deliberately striking a motorcycle, has also made the case unusually visual and verifiable compared to many alleged crimes that rely mostly on witness testimony.
For safety researchers and human resources professionals, cases involving coworkers and alleged fixation or unwanted romantic interest, like the dynamic prosecutors describe between Sorensen and Peterson, are also frequently cited as a reason workplaces establish clear boundary and harassment reporting procedures.

What Happens Next In The Legal Process?
Sorensen’s case will now move through the standard felony process in King County Superior Court. Between the pre-trial conference and the scheduled trial date, both the prosecution and defense will typically exchange evidence through discovery, file and argue pretrial motions, and potentially discuss a plea agreement, though nothing in current reporting indicates plea negotiations are underway.
If the case proceeds to trial as scheduled on September 28, 2026, prosecutors will need to prove beyond a reasonable doubt that Sorensen acted with intent to cause serious harm when he struck Langdon.
Quick Tip: If you want to follow how the case develops, King County Superior Court maintains public online case records, and outlets like KOMO News and the Issaquah Spotlight have been covering each court date directly rather than relying on secondhand reporting.
