Anson Clinton Murdered by Haymon Klein, Mark DePrey, and others, Old Lyme, Connecticut, United States

Case Summary

In March 1994, 28-year-old Anson 'Buzz' Clinton was shot to death on a highway connector off Interstate 95 in Connecticut. Investigation revealed a hit-for-hire plot stemming from an intense family custody conflict over Clinton's stepdaughter, Rebecca. Clinton's sister-in-law, attorney Beth Carpenter, allegedly solicited her law firm boss and married lover, Haymon Klein, to eliminate Clinton to prevent him and her sister Kim from moving the child to Arizona. Klein hired drug dealer Mark DePrey for $8,500 to execute the killing. DePrey lured Clinton under the guise of buying a tow truck and shot him five times. All three co-conspirators were eventually convicted and sentenced to prison terms, with Carpenter receiving life without parole in 2002.

AI Intelligence Assessment

Relationship Pattern

Custody Conflict

Pattern Analysis

The incident highlights how an ongoing family custody dispute fused with an intense workplace extramarital affair to generate a fatal conspiracy. Beth Carpenter sought total control over her niece's upbringing, fearing her sister and brother-in-law would relocate to Arizona. Leveraging her emotional hold over her employer and lover, Haymon Klein, she motivated him to arrange a contract killing using a third-party hitman.

Investigative Notes

Police initially lacked leads until a tip in May 1994 identified Mark DePrey. DePrey confessed and named attorney Haymon Klein as the paymaster. Klein fled when police sought his arrest, but was located in California in 1996 after Beth Carpenter provided key payphone details to police. Klein subsequently entered a plea deal to testify against Carpenter. Extradited from Ireland in 1999 after Connecticut agreed not to seek the death penalty, Carpenter was tried in 2002, convicted on all charges, and sentenced to life without parole.

Investigation Confusion

The primary investigative difficulty was establishing direct physical evidence linking Beth Carpenter to the contract killing. The prosecution's case rested almost entirely on co-conspirator testimony from Haymon Klein, who had severe credibility issues, including cocaine addiction, an antisocial personality disorder diagnosis, and a history of dishonesty.

Case Reconstruction / Puzzle Pieces

The prosecution argued that Beth Carpenter initiated the homicide plan to stop Buzz Clinton from moving her niece to Arizona. After an initial hesitation, a false report of injury to the child prompted Klein to reactivate hitman Mark DePrey. DePrey staged a vehicle purchase meeting, led Clinton onto a highway connector, and shot him five times.

Risk Assessment

Escalating legal disputes over child guardianship accompanied by extreme emotional obsession in an extramarital dynamic represent high-risk warning signs. The willingness to resort to illegal, violent solutions grew out of unmanaged domestic hostility combined with access to criminal contacts through a legal practice.

Key Takeaways

Intense familial custody conflicts can escalate to extreme violent outcomes when external individuals are drawn into the grievance. The case demonstrates the power of co-conspirator testimony in organized contract killings where direct physical evidence against the orchestrator is absent.

AI Case Q&A

What early signals mattered most?

The probate court battle over guardianship of Rebecca and explicit friction between Beth Carpenter and Buzz Clinton indicated severe, unresolvable domestic conflict.

Which clues helped connect the case?

A tipster naming drug dealer Mark DePrey provided the breakthrough clue, leading to his confession and exposure of the entire conspiracy chain.

Which evidence types appeared strongest?

The strongest evidence consisted of the detailed confession by triggerman Mark DePrey and co-conspirator testimony from Haymon Klein, supported by telephone records.

Witness / Eyewitness Statements

Motorists reported seeing Buzz Clinton's parked Firebird with the driver's door open and observing a tall, lanky man enter a blue car parked behind it before driving away rapidly.

How did follow-up reports change the understanding?

Initial dead ends dissolved when DePrey confessed. Klein later reversed his stance after fleeing, agreeing to a plea deal that shifted focus onto Beth Carpenter as the central instigator.

What remained unclear?

Whether Haymon Klein acted entirely independently to impress Beth Carpenter or directly under her explicit direction remained a subject of ongoing legal argument during appeals.
