Former Dentist Faces Murder, Arson Charges in Tenant’s Death
A former California dentist is now facing serious charges, including murder and arson, in connection with the fatal shooting of his tenant. The San Francisco District Attorney’s Office announced Thursday that Philippe Chagniot, 68, has been charged with murder. The victim, identified by multiple outlets as 58-year-old Eric Bigone, was reportedly shot and killed in an ambush in the Outer Sunset neighborhood.
Details of the Alleged Attack
According to officials, the incident occurred around 5 a.m. on May 17. Prosecutors allege that Chagniot, disguised in a mask and dark clothing, rode a bicycle to Bigone’s residence. Before the shooting, the district attorney’s office stated, Chagniot allegedly spray-painted surveillance cameras in the vicinity and then set fire to a car parked in front of Bigone’s home. Investigators later recovered surveillance footage.
When Bigone emerged from his house with a shovel, reportedly attempting to extinguish the burning vehicle, Chagniot emerged from a hiding spot. Prosecutors claim Chagniot then used a silenced, fully automatic weapon to shoot Bigone. The landlord is further accused of standing over the fallen victim and firing additional shots before leaving the scene on his bicycle.
Investigation and Arrest
The motive behind the alleged attack remains unclear at this time. Chagniot was taken into custody on Wednesday and transported to the San Francisco County jail. A search warrant executed at Chagniot’s residence reportedly yielded evidence linked to the murder.
Beyond the murder charge, Chagniot faces accusations of arson, unlawful possession of an automatic firearm, and other related offenses. Information regarding legal representation for Chagniot was not immediately available.
Victim’s Life and Community Reactions
Eric Bigone was described by loved ones as someone who had overcome significant challenges, including past struggles with alcoholism. He was reportedly involved in teaching youth boxing and supported others in recovery through Alcoholics Anonymous. Bigone was employed by the San Francisco Public Utilities Commission and also performed as a singer in a band named Whiskey Business.
One family member, who wished to remain anonymous, called Bigone a “legendary person.”
Neighbors of Philippe Chagniot expressed shock at the accusations. Joy Gayle, who lives next door and has known Chagniot for 35 years, described him as a “great neighbor” and a “great man.” Gayle also mentioned that Chagniot had previously been her dentist.
Records indicate Chagniot held a dental license in California since 1985, which expired in 2024. The exact circumstances leading to the confrontation and subsequent charges are still under investigation.
