While detectives have reviewed Johnson’s posts, police are not considering the eclipse to be a precipitating or contributing factor to the slayings “because we just don’t know why she did what she did,” Golan told The Associated Press.
“We’ve taken all the facts we can, but without being able to interview her and without having something more tangible than a post on X, I don’t know how much weight you can give to somebody (saying) there’s an apocalypse and attribute it to one of the most horrific murders we’ve had in LA,” Golan, who is head of the homicide unit investigating the case, said.
Authorities say Johnson and her partner, 29-year-old Jaelen Allen Chaney, had an argument around 3.40am on Monday in their apartment in Woodland Hills, about 42km north-west of downtown LA.
Johnson stabbed Chaney and fled with her children, an eight-month-old girl and her nine-year-old sister, in a Porsche Cayenne.
Johnson then drove along Interstate 405 in Culver City and threw her daughters out of the moving SUV around 4.30am, police said.
The baby was pronounced dead on the road, but the older daughter — who witnessed the stabbing — survived with moderate injuries.
Johnson travelled south-west to Redondo Beach, where a half-hour later she was driving over 160km/h and crashed into a tree.
The LAPD is investigating whether the fatal solo crash was an apparent act of self-harm.
The Los Angeles Times first reported on Johnson’s social media activities in connection with the killings.
“Get your protection on and your heart in the right place,” she posted April 4 to more than 105,000 followers on X.
“The world is very obviously changing right now and if you ever needed to pick a side, the time to do right in your life is now. Stay strong you got this.”
On April 5, she posted in all caps, “Wake up wake up the apocalypse is here. Everyone who has ears listen. Your time to choose what you believe is now.”
Her social media also included a mix of antisemitic screeds, conspiracy theories about vaccines and warnings about the end of the world alongside astrological predictions and positive affirmations.
Also on April 5, she posted the word “LOVE” dozens of times.
Her personal website offers a variety of services including “zodiac healing work,” “alcohol balancing system” and an “aura cleanse”.
Johnson’s internet presence and online following dates back years.
The Fader, a music magazine, interviewed her in 2016 as an astrology personality.
Golan said there were no calls for police to respond to the couple’s apartment prior to Monday’s killing, when neighbours called 911 after seeing the door open.
Johnson did not have a felony criminal record in California and there were no indications of reported domestic violence.
Detectives did not immediately link the Woodland Hills slaying to the daughters, Golan said.
He was in the San Fernando Valley neighbourhood when he started getting push alerts from news organisations on his mobile phone about the infant’s death on the roadway in Culver City.
Investigators realised there might be a connection between two missing children from the family’s apartment and the tragedy on the interstate.
“I was like ‘Oh, there’s two young girls who were stranded on the 405 Freeway.’ That is such a random and terrible thing to hear about. And we knew there were two young children,” Golan continued.
“We were setting up an Amber Alert.”

Golan said detectives discovered candles and cards inside the apartment, but he was not sure whether they were tarot cards.
“They didn’t look like your standard deck of cards that you would play poker with,” he said.
The solar eclipse’s path of totality stretched from Mazatlán, Mexico, to Newfoundland, Canada, a swath approximately 185km wide.
Revellers were engulfed in darkness at state parks, on city rooftops and in small towns when the moon blocked out the sun, though Southern California only saw a partial eclipse that peaked at 11.12am.
Across the globe, the celestial event spawned fears of the apocalypse and other suspicions rooted in religion and spirituality.
But Golan noted that others who posted online about their eclipse-related worries did not commit violence like Johnson.
“How many people wrote about it,” he said, “and didn’t go out and murder somebody?”
