Who Is Sheila Davalloo?
Sheila Davalloo is an Iranian–American woman whose name became internationally known after she was convicted of two brutal crimes rooted in a twisted office love triangle.

Her outwardly successful life—as a data‑management and research professional at major pharmaceutical companies—contrasted sharply with the hidden obsession and violence that later defined her.
Because of her role in these high‑profile criminal cases, “Sheila Davalloo” is now a frequently searched true‑crime keyword, especially in connection with media coverage from Oxygen’s Snapped and ITV’s Killer Women With Piers Morgan.
Sheila Davalloo – Biography Snapshot
Early Life and Education
Davalloo’s early years were marked by ambition and discipline, traits that helped her excel academically. She performed well in school and later pursued higher education in biochemistry, eventually earning a master’s degree, which opened doors to a professional career in the pharmaceutical industry. Her background as a smart, driven immigrant daughter played a key role in shaping how she presented herself in public—respectable, articulate, and outwardly stable.
This polished image made her later crimes even more shocking to colleagues and acquaintances who had only ever seen her as a competent, seemingly normal working‑class woman.
Career at Purdue Pharma and Social Circle
Sheila Davalloo worked in the pharmaceutical world, including positions at Purdue Pharma L.P. in Stamford, Connecticut, where she held roles such as Global Manager in data management. The company’s high‑pressure environment placed her in close daily contact with colleagues, which is where her personal drama began to unfold.
It was at Purdue that she met Nelson Sessler, a fellow researcher, and the two began an affair. However, the relationship changed when Sessler shifted his attention to another coworker, 32‑year‑old Anna Lisa Raymundo, who became both his romantic partner and Sheila’s perceived rival.
The Murder of Anna Lisa Raymundo
On November 8, 2002, Sheila Davalloo traveled from Westchester, New York, to Stamford, Connecticut, to Anna Lisa Raymundo’s condominium. What followed was a savage attack: Davalloo stabbed Raymundo multiple times, killing her in what authorities described as a premeditated act of jealousy‑driven rage.
The prosecution argued that Davalloo had planned the murder to eliminate Raymundo and remove the obstacle standing between her and her desire to rekindle a relationship with Sessler. The case gained national attention not only because of the brutality of the crime but also because of the professional, seemingly ordinary background of the accused.
The Attempted Murder of Her Husband, Paul Christos
The deadly pattern in Davalloo’s behavior did not begin with Raymundo. Earlier, in 2001, she was arrested in connection with the attempted murder of her husband, Paul Christos. Prosecutors contended that she had poisoned him with anti‑seizure medication, leading to a severe medical emergency that initially masked the criminal intent behind his symptoms.
In a non‑jury trial in New York, she was convicted of attempted murder and sentenced to 25 years in state prison. The case was presented as part of a larger pattern of obsessive control and extreme jealousy, painting a picture of a woman willing to harm loved ones to protect or reclaim a romantic relationship.
Trial, Conviction, and Sentence
Years after the attempted murder of her husband, law enforcement reopened the investigation into Anna Lisa Raymundo’s death, linking Sheila Davalloo to the crime scene through circumstantial evidence and motives rooted in the same love triangle. In 2012, a Connecticut jury convicted her of first‑degree murder in the stabbing death of Raymundo.
She received a 50‑year prison sentence for that murder, to be served after she completed her 25‑year term in New York for the attempted murder of Paul Christos. This meant that Sheila Davalloo effectively faced a life behind bars, with no possibility of parole for the Raymundo murder.
Psychology and Motive: Obsession and Jealousy
What sets the Sheila Davalloo case apart from many true‑crime stories is the clear psychological thread of obsession and jealousy. Experts and prosecutors described her actions as driven by a pathological need to control key relationships in her life—at the cost of others’ lives.
The “love triangle” narrative involving Davalloo, Sessler, and Raymundo became a focal point in media analyses, with commentators highlighting how workplace affairs and emotional insecurity can spiral into deadly violence. For readers searching for “Sheila Davalloo,” understanding this motive is often the central reason they land on an article about her.

In Piers Morgan’s Killer Women With Piers Morgan, Davalloo broke her years‑long silence and spoke directly about the events surrounding Raymundo’s murder, giving viewers a rare, first‑person perspective on the case.
