On Oct. 10, 2017, 67-year-old Beverly Hills widow Violet Yacobi was discovered lifeless on the marble floor beneath her second-story staircase. Her children, Daniel and Dina, told police they found her that evening; early responders considered the possibility of suicide or an accidental fall. But veteran investigators quickly grew skeptical.
Detectives George Elwell and Mark Schwartz, called to the scene, noted inconsistencies that made a fall seem unlikely: dust undisturbed across the entire railing, the body positioned so that Violet’s feet were tucked under the stairs, and apparent marks on her face and neck. There were no signs of a break-in and Violet’s valuables remained in the home. Family members said Violet had been quietly grieving — she had canceled domestic help and marked the first anniversary of her husband’s death — but her injuries and the scene suggested other possibilities.
An autopsy completed Oct. 13 determined the official cause of death was asphyxia by neck compression. The medical examiner recorded ligature-type markings and petechiae around the eyes and face, findings prosecutors would later argue were classic signs of strangulation. The ruling converted the inquiry into a homicide investigation, and detectives refocused on the people closest to Violet.
Attention soon turned to her son, Daniel Yacobi, a dentist who lived nearby. Detectives said Daniel’s behavior during the initial walkthrough and later interviews was odd: overly eager cooperation, conflicting accounts about performing CPR, and evasive answers about where he had been the night his mother died. Investigators also found disturbing out-of-court behavior — while in an interview room, Daniel texted his sister asking them to “keep the story straight” about who performed chest compressions.
Cellphone records and security footage began to contradict Daniel’s account. He had told police he worked in Inglewood the night of Oct. 9 and then went straight home, never visiting his mother. But cellphone location data placed him in Beverly Hills that day, and Nest camera footage from his house showed him arriving home around 8 p.m. Investigators also recovered his car on neighbor video circling Violet’s block in the afternoon, and Facebook metadata later linked him to coordinates at or near his mother’s house between 6:39 and 7:48 p.m. that evening.
Prosecutors presented a broader digital trail that they said showed planning and consciousness of guilt: internet searches dating to August 2017 on unexplained deaths, choke holds, bruising from chokeholds, and later a search for how to lift latent fingerprints from human skin. Investigators also reported finding Daniel searching his own computer for latent fingerprint techniques less than an hour after he returned home the night he had been at his mother’s house. DNA identified as Daniel’s was recovered under Violet’s fingernails, which prosecutors argued was consistent with a struggle.
Motive, prosecutors said, was financial. Violet and her late husband had amassed an estate estimated at roughly $13 million; Daniel stood to inherit a large share. Prosecutors described Daniel as resentful and financially strained despite outward appearances of a successful life. Testimony included witnesses who said he had recently been anxious about money and had inquired about inheritance tax weeks before Violet’s death.
Investigators arrested Daniel Yacobi on Feb. 12, 2018. He was held without bail and spent more than seven years in custody because of court delays before finally going to trial in July 2025.
The trial became a clash of medical experts and competing narratives about how Violet died. The prosecution relied on the autopsy’s conclusion of asphyxia by neck compression and pointed to abrasions on Violet’s jawline and neck, spinal and rib fractures, the absence of disturbance on the staircase railing, and the digital and physical evidence tying Daniel to the scene and to searches about chokeholds and fingerprint removal. Prosecutors argued the injuries and bruising were consistent with manual strangulation and a forceful assault from behind.
The defense advanced an alternative explanation: a catastrophic medical event followed by a fall. Forensic pathologist Dr. Lary Simms testified that Violet had an arteriovenous malformation (AVM) in the brain stem that could have hemorrhaged, rendering her disoriented and causing her to strike the railing and fall. Simms disputed the autopsy’s findings, characterizing some of the reported petechiae as unrelated skin changes and some neck markings as skin folds, not signs of strangulation. He and other defense experts also criticized the original autopsy for omissions, arguing some fractures were missed or mischaracterized and that the evidence could support an accidental fall.
Prosecutors acknowledged flaws and omissions in the initial autopsy report but countered that photographic evidence showed injuries not explained by a fall from the landing, and that multiple experts — including a neuropathologist and a second deputy medical examiner called by the prosecution — supported the finding of neck compression as the cause of death. They also emphasized the circumstantial and digital evidence: cellphone locations, security camera footage, Facebook coordinates, searches about chokeholds, and the DNA found under Violet’s fingernails. The prosecution urged jurors to view the electronic record as a timeline placing Daniel at his mother’s home when she was alive and leaving after she was dead.
After three weeks of testimony and nearly eight years since Violet’s death, the jury deliberated for about five-and-a-half hours over two days. In late August 2025 they returned a unanimous verdict: guilty of first-degree murder for financial gain. The conviction carries a mandatory sentence of life in prison without the possibility of parole.
The case tore the family apart and divided observers. Detectives said the evidence — physical injuries, the DNA under the victim’s nails, the digital footprint and motive — pointed to a calculated killing for inheritance. Defense attorneys and some experts argued the autopsy was flawed, the injuries could be explained by a fall or medical event, and reasonable doubt remained. In the end, the jury sided with the prosecution.
Violet Yacobi’s death and the long legal battle that followed left a fractured household and raised broader questions about forensic practice, the weight of digital evidence, and how jurors evaluate competing expert opinions in a case where medicine, motive and technology all intersected.
