Authorities are investigating a woman's "violent death" at the historic Spreckels Mansion in Coronado, a San Diego sheriff's official said.
The death of the woman, whose name and age have not been released, is considered "suspcious" in nature, Capt. Tim Curran said.
The deceased woman was one of two guests staying at the home, located on the 1000 block of Ocean Boulevard, Coronado police said. The other guest, a male, called 911 after 6:30 p.m. Wednesday to report a possible death at the house.
Coronado police responded and found a woman who was in "distress," a sheriff's spokeswoman said in a release. Officers began life-saving measures, and the Coronado Fire Department and paramedics arrived on the scene.
The woman was pronounced dead shortly thereafter. Aerial helicopter footage showed a body in the mansion's courtyard.
At 8:20 a.m., Coronado police, which does not have a full-time homicide unit, requested the San Diego County Sheriff's Department's assistance.
Shortly before noon Wednesday, Curran said officers were awaiting a warrant. The investigation is ongoing.
According to the San Diego Accessors Office, the property's owner is listed as Jonah Shacknai, 54, founder and CEO of Medicis, a pharmaceutical company based in Scottsdale, Ariz.
A message with a company employee was not immediately returned, and the employee said she would not disclose whether Shacknai is in Scottsdale.
The company released an official statement late Wednesday afternoon:
The Medicis family is deeply saddened to learn of a tragic incident at a California property owned by Jonah Shacknai. Our thoughts are with Jonah and his family and ask that the family’s privacy be respected during this difficult period. At this time, the Company has no further comment.
The mansion, one of the most storied residences in Coronado, was built in 1908 as a beach home for John D. Spreckels, who owned the nearby Hotel del Coronado.
The 27-room main house includes six bedrooms, 4.5 baths, basement, attic, an unfinished wine-storage room used during Prohibition and a guest home.
Police were called to the same home Monday for an injured child.
