The Poison Tree

The Poison Tree: A True Story of Family Violence and Revenge is a 1986 non-fiction crime biography by Alan Prendergast. It was nominated for an Edgar Award for Best Fact Crime. Before publishing this book, Prendergast had covered the Jahnkes' story for Rolling Stone magazine. The Poison Tree tells the story of Richard and Deborah Jahnke, two adolescents who conspired to kill their father in 1982, after being subjected to his verbal and physical abuse their entire lives. A made for TV movie based on their story and starring Justine Bateman as Deborah Jahnke, aired in 1985.

Prendergast's comprehensive account begins with the meeting of Richard C. Jahnke and his future wife, Maria de Lourdes Rodriguez. They met on November 16, 1962, near San Juan Puerto Rico, on a bus. Twenty-year-old Maria was on her way to work, and Richard, only eighteen at the time, was a private posted at the nearby base of Fort Brooke. He had a free day that he had decided to spend sightseeing. The two eyed each other, but perhaps nothing more would have occurred had the bus not had engine trouble that forced it to stop. After all the passengers disembarked, Maria was the only person who would speak English to Richard, and she helped him find the bus he needed to get back to Fort Brooke.

They started dating soon after. Early on, Maria noticed that Richard seemed to be prone to jealousy, but they got along well otherwise; she found his mischievous nature appealing. Maria was living in poor conditions at the time with her mother, who seemed to care little about her daughter's welfare. When Richard proposed to Maria, she accepted, and they finally married on June 6, 1964. Although the couple told their friends and families that they were going to go honeymoon in Jamaica, they actually rented a cheap place in southern Puerto Rico instead. Maria would later note that this started a precedent of secrecy surrounding their marriage, one that would deepen over time.



On March 16, 1965, Maria gave birth to the couple's first child, a daughter named Deborah Ann. In less than a year, she became pregnant again. Richard, still with the military, was re-assigned to Fort Ord, California, where the couple moved next. It was in California that their next child, son Richard John, was born. However, by this time, the tenor of Richard and Maria's relationship had changed. Things had begun to sour; Richard had become physically and verbally abusive towards his young children, and his wife. The only peaceful times during the younger Jahnkes' lives came when their father was sent on unaccompanied tours elsewhere. Richard did such a poor job while in Germany that he was discharged, but he got a job soon afterward with the Internal Revenue Service. The Jahnkes’ continued to move frequently, before landing, finally in Cheyenne, Wyoming in 1981. Their new place was located on the edge of town, and to the best of anyone's recollection, the Jahnkes’ were a quiet family that mostly kept to themselves.

Things were not quiet, however, within the Jahnke household. Richard Sr.'s abuse had continued, and in some ways escalated. He amassed an enormous arsenal of guns – which would later prove his downfall. The Jahnke siblings, close in age and allied against the tyranny of their father, shared a close bond despite their many superficial differences. Richard Jr. found solace in his school's ROTC, which was the one thing he felt he was good at. He grew close to his teacher, Major Robert Vegvary, who saw a bright military future ahead for him. Deborah was not particularly popular at her school, and many of her peers found her odd. She had taken an interest in art, however, and had found a sort of mentor in her art teacher, Eve Whitcomb, who encouraged her interests. When eventually their lives at home had become intolerable, the siblings finally asked for help of the adults around them at school – but their concerns were dismissed.

The Jahnkes’ home life came to a boiling point, finally, in November of 1982. While the two elder Jahnkes went out in celebration of the twentieth year anniversary of their meeting, Richard Jr. and Deborah planned their father's death. Richard rounded up the family’s pets and locked them in the basement. He selected several guns from his father's extensive cache of weaponry and hid them all over the house. He instructed his sister to wait in the living room, with an M-1 carbine, which she did. At around 6:30 p.m., while she was watching the clock, Deborah heard gunshots from the garage. Soon after, a stunned Richard Jr. emerged, grabbed his sister, and they escaped into the night. As Prendergast writes in his Rolling Stone article, “Within hours, Richard and Deborah were in jail. Within days, they were national news.”



The Poison Tree is in many ways a textbook example of true crime biography: based on a significant journalistic investigation, it pieces together the story of those involved in a horrific and notorious crime and presents it for public consumption. The genre is a familiar one today, and by modern standards, the Jahnke story seems almost too pat, Richard and Deborah's crimes too well justified to seem controversial. Perhaps unexpectedly, then, Prendergast's book helps to illuminate just how cozy American reading audiences (in particular) have come to be with non-fictional accounts of violent crime since the shock waves made by Richard J. Jahnke and his sister in the 1980s.
