Los Angeles – Under the weight of a tense courtroom hush, a once-promising biotech entrepreneur faced the consequences of a scheme that turned deadly cold, much like the Vermont snow where the victim was found.

The Shocking Guilty Verdict

Imagine building an empire in the high-stakes world of biotechnology, only to watch it crumble under the glare of a murder conviction. That’s exactly what happened to Serhat Gumrukcu this week. After a trial filled with twists, a federal jury in California delivered a resounding guilty verdict on charges of murder-for-hire, conspiracy, and wire fraud.

The decision came swiftly, underscoring the strength of the evidence against him. Gumrukcu, now 42, showed little reaction as the foreman read the counts. For the victim’s family, it marked a bittersweet end to years of grief and uncertainty.

This isn’t just a story of corporate ambition gone wrong—it’s a stark reminder of how far some will go to protect their secrets.

Who Is Serhat Gumrukcu?

Serhat Gumrukcu started as a Turkish immigrant chasing the American dream in biotech. He founded Enochian Biosciences, later rebranded as Renovaro, focusing on treatments for diseases like HIV and cancer. At its peak, the company drew big investments and even caught the eye of high-profile figures in medicine.

But beneath the success, Gumrukcu dabbled in riskier ventures, including international oil trading. That’s where his path crossed with the man who became his target. Friends described him as charismatic, yet prosecutors painted a picture of a man willing to eliminate threats to his reputation.

His trial revealed a web of lies that extended from boardrooms to back alleys, showing how unchecked power can corrupt even the brightest minds.

The Tragic Victim: Gregory Davis

Gregory Davis was the kind of guy who put family first—a Vermont resident and father of six who balanced work with coaching little league and family barbecues. At 39, he seemed to have it all figured out until a business partnership turned sour.

Davis stumbled into Gumrukcu’s world through an oil deal promising quick riches. When it fell apart, he threatened to expose what he saw as fraud. That decision cost him everything; his body was discovered in a snowbank in 2018, shot execution-style.

His widow’s words in court cut deep: she now raises seven children alone, their lives forever altered by one man’s greed.

How the Murder Plot Unfolded

The scheme read like a thriller novel, but it was all too real. Gumrukcu allegedly enlisted his friend Berk Eratay to find a hitman. Eratay then looped in middleman Aron Ethridge, who hired Jerry Banks as the triggerman for a reported $20,000 payout.

Prosecutors laid out a trail of encrypted messages, wire transfers, and witness testimonies that pieced together the conspiracy. Banks, facing his own charges, flipped and detailed the cold-blooded execution in Vermont. It was a chain of desperation that Gumrukcu couldn’t deny.

From initial planning in California to the grim discovery in the Northeast, every step highlighted the plot’s calculated cruelty.

The Spark: A Failed Oil Deal Gone Deadly

It all boiled down to a lucrative but flawed oil trading agreement between Gumrukcu and Davis. What started as a potential windfall quickly soured when shipments didn’t materialize and funds vanished. Davis, feeling duped, confronted his partner and vowed to alert authorities.

Gumrukcu saw this as an existential threat to his biotech empire and personal fortune. Instead of resolving it legally, he opted for a permanent solution. Court documents showed frantic communications in the weeks leading up to the murder, revealing his mounting panic.

This case exposes the shadowy underbelly of international deals, where billions are at stake and ethics often take a backseat.

Accomplices and the Road to Justice

The plot involved a tight-knit group, each playing a pivotal role. Here’s a quick breakdown of the key players:

  • Berk Eratay: Gumrukcu’s close confidant who kickstarted the search for a killer.
  • Aron Ethridge: The intermediary who connected the dots to the hitman, now serving time himself.
  • Jerry Banks: The actual shooter, whose cooperation helped seal the conviction.
  • Serhat Gumrukcu: The mastermind, convicted and awaiting sentencing.

Investigators from the FBI unraveled the connections over years, using digital forensics and undercover work. Eratay and Ethridge had already pleaded guilty, paving the way for Gumrukcu’s downfall. Banks’ testimony was the hammer that nailed the case shut.

Their involvement shows how loyalty can blind people to the consequences of crossing moral lines.

What’s Next for Gumrukcu and the Biotech World?

With a mandatory life sentence on the table, Gumrukcu’s future looks bleak. Sentencing is set for later this month, and prosecutors are pushing for the maximum. His company, meanwhile, distances itself, but the scandal could ripple through investor confidence in the sector.

For the Davis family, closure comes at a high emotional cost. They’ve vowed to honor Gregg’s memory by advocating for stronger protections in business dealings. It’s a call to action for others navigating high-risk partnerships.

This verdict serves as a cautionary tale: no amount of success justifies silencing the truth.

Key Takeaways

  • A failed oil deal escalated into a murder-for-hire plot, claiming an innocent father’s life.
  • Gumrukcu’s conviction highlights the dangers of unchecked ambition in business.
  • The victim’s family urges vigilance in partnerships to prevent similar tragedies.
