Michael Farrar: The Ricin Poisoning, Fire, and Debora Green Case

The Michael Farrar and Debora Green case refers to a 1995 Kansas crime in which Farrar, a Kansas City-area cardiologist, was poisoned with ricin by his estranged wife, Dr. Debora Green, who then set fire to their Prairie Village home, killing two of their three children. Farrar survived, continued practicing medicine at North Kansas City Hospital for decades, and died on August 23, 2023, at age 68. Green pleaded no contest in 1996 and is serving a Hard 40 life sentence at the Topeka Correctional Facility.¹²

Who Michael Farrar Was

Born March 3, 1955, in Lawrence, Kansas, Michael William Farrar trained at the University of Missouri–Kansas City School of Medicine and completed postgraduate work at the University of Cincinnati Medical Center in 1982. He began practicing at North Kansas City Hospital in 1988 as a founding member of Northland Cardiology, later Meritas Cardiology, and eventually served as president of the hospital’s medical staff.³⁴

He was married to Debora Green, an oncologist who had left practice to raise their three children: Tim, Kate, and Kelly. By 1995 the marriage was failing. A fire of undetermined origin damaged the family’s Missouri home in May 1994 shortly after Farrar had raised doubts about the relationship; no charges followed at the time, though investigators later revisited it.⁵

The Ricin Poisoning

Between August and September 1995, Farrar was hospitalized three times with severe gastrointestinal symptoms that improved in the hospital and returned each time he went home.⁴ The cause turned out to be ricin, a toxin derived from castor beans, which Green had been mixing into his food.

On September 25, 1995, police responding to a domestic disturbance at the Prairie Village home found packets of castor beans in Green’s purse.² Farrar, once he learned what the beans could be used for, began connecting his recurring illness to specific meals Green had prepared. Lab tests confirmed high levels of ricin antibodies in his blood.⁵ The poisoning caused lasting damage; Farrar eventually required surgery on both his heart and his brain.

The Prairie Village Fire

Farrar moved out on October 5, 1995. On the night of October 23, he dropped the three children back at the house around 8:45 p.m. after a hockey game. He and Green argued by phone later that evening.¹

Just after midnight on October 24, a 911 hang-up call came from 2517 Canterbury Court. Fire crews arrived at 12:27 a.m. to find the six-bedroom house fully engulfed. Thirteen-year-old Tim died of burns. Six-year-old Kelly died of carbon monoxide poisoning in her bed. Ten-year-old Kate escaped by climbing onto the roof and jumping. Green got out. Farrar was not there.¹⁵

He filed for divorce the following day.²

Evidence Against Debora Green

The Eastern Kansas Multi-County Task Force reported on November 10, 1995, that the fire was “an intentionally set incendiary fire caused by ignition of a liquid accelerant applied throughout the structure on the main and second floors.”¹ Investigators documented multiple points of origin, pour patterns, unusual low-burn damage, and isoparaffins consistent with ignitable liquids in the debris. An empty accelerant bottle was recovered at the scene.⁵

Physical evidence pointed at Green herself. Soot on the doorjamb of her bedroom showed the door had been open when the fire started, contradicting her account. Her bathrobe was burned, and her hair showed singeing. Flammable liquid had been poured on the staircase, the children’s only route down from the second floor.⁶ In the weeks before the fire, Green had checked out library books about intrafamilial homicide.⁷

The Plea and Hard 40 Sentence

Green was arrested in late November 1995 and held on $3 million bond. Johnson County District Attorney Paul Morrison charged her with aggravated arson, two counts of first-degree murder for the deaths of Tim and Kelly, and two counts of attempted first-degree murder covering Kate’s endangerment in the fire and the ricin poisoning of Farrar.⁸

A psychologist declared her competent to stand trial in early 1996.¹ On April 17, 1996, Green pleaded no contest to two counts of capital murder, one count of attempted capital murder, one count of attempted first-degree premeditated murder, and one count of aggravated arson. In exchange, the state took the death penalty off the table and recommended concurrent sentences.⁹

At the plea hearing, Green said she wanted to spare her family and surviving daughter further suffering, while acknowledging the state could produce “substantial evidence” that she set the fire.¹⁰ The judge imposed a controlling Hard 40 life sentence, meaning no parole eligibility for 40 years, with the remaining sentences to run concurrently.¹

Failed Appeals

Green spent years trying to unwind her conviction and sentence. None of it worked.

In 2004, she moved to withdraw her plea, arguing that newer fire-investigation standards, particularly on flashover phenomena in NFPA 921, undermined the original arson findings. The Johnson County district court denied the motion in 2005, calling the new expert testimony a competing interpretation of old evidence.¹ At that hearing, Morrison told the court that if the plea were withdrawn, “we’ll be more than happy to put the death penalty back on the table.”¹⁰

The Kansas Supreme Court affirmed that denial in 2007. A 2008 federal habeas petition was denied by the U.S. District Court for the District of Kansas, and in 2009 the Tenth Circuit denied a certificate of appealability and dismissed her case.¹⁷ In 2015, Green asked Johnson County District Judge Brenda Cameron to vacate the Hard 40 sentence based on recent Kansas Supreme Court decisions about jury involvement in sentencing; Judge Cameron ruled the decisions did not apply retroactively and noted Green had already avoided the death penalty through her plea.¹¹

Where Debora Green Is Now

Green remains incarcerated at the Topeka Correctional Facility. Per the Kansas Department of Corrections, she will not be eligible for parole until November 1, 2035, when she will be 84.¹¹

Farrar’s Life After the Case

After the deaths of two of his children and the surgeries that followed his poisoning, Farrar pulled back from public life. He told The Kansas City Star in 1997: “To me, I’d just as soon people forget about the whole thing. I just want to stay out of the limelight. Just go on with my life.” He remarried, settled in Smithville, Missouri, with his wife Angela, and continued practicing cardiology at North Kansas City Hospital for decades. His one notable public reappearance was a short 2018 tribute video the hospital produced about his career.²

He died in Smithville on August 23, 2023, at 68. He was survived by Angela, his daughter Kate Donaldson and her husband Clint, his granddaughter Norah, his parents, and two sisters. Services were held August 30 at Avondale United Methodist Church in Kansas City.¹²³

Books, TV, and the Lifetime Movie

The case reached a broad audience through several adaptations. Ann Rule’s 1998 true-crime book Bitter Harvest: A Woman’s Fury, a Mother’s Sacrifice covered the marriage, the poisoning, and the fire, attributing Green’s actions to alcoholism, prescription drug addiction, and rage over Farrar’s departure.¹³ A 1999 Forensic Files episode, “Ultimate Betrayal,” walked through the forensic investigation. In 2021, Lifetime released A House on Fire, with Stephanie March playing Green.⁵
