More than a year after a pair of mysterious deaths at the home of pharma CEO Jonah Shacknai, there's a new twist in the case.
Shacknai's 6-year-old son Max died in July 2011 after taking a tumble inside his Coronado, Calif. summer home.
Two days after the boy's fall, Shacknai's 32-year-old girlfriend, Rebecca Zahau, who was watching Max when he apparently fell, was found dead herself.
Zahau was found hanging naked, with her feet and legs bound. Her death was ruled a suicide.
Shacknai's ex-wife Dina now claims Max's fall was no accident and Zahau was somehow responsible, NBC San Diego reported this week.
In light of new developments, Business Insider decided to take a look at everything we know about the scandal that plagued Medicis Pharmaceutical CEO Jonah Shacknai, who's not a suspect in the case.
A rocky marriage that finally began to crumble in 2009.
Jonah and Dina lived in Paradise Valley, a wealthy Arizona community near the home base of Medicis, the LA Times reported in July 2011.
They were highly respected and volunteered together at local non-profits including the Whispering Hope Ranch Foundation.
But they had fights that on occasion became violent, the Times reported.
Jonah went to the police and said Dina had tried to choke him back in 2008. The next year, as their marriage was imploding, Dina reportedly told police her husband elbowed her in the chest.
Then Jonah met an ophthalmic technician who was said to be "full of life."
It's not clear when Shacknai met Rebecca Zahau, according to the July 2011 article in the LA Times.
She was an ophthalmic technician near Phoenix, and her ex-boss described her as being wonderful with patients.
"Rebecca was a person who was full of life," Michael Trier, chief executive of Horizon Eye Specialists & Lasik Center, told the LA Times.
The couple eventually began spending time at Shacknai's historic mansion in Coronado, Calif. known as the Spreckels Mansion.
In September 2010, Dina asked Jonah not to leave their son, Max, alone with Rebecca.
Dina told HLN this week Jonah's new girlfriend lied about her background when the two women met.
Rebecca neglected to say she had been married or caught shoplifting, Dina Shacknai said.
The now-deceased woman also gave Dina a last name she'd never used before in this country, according to Dina. So Max's mom told her ex not to leave Zahau alone with her son.
"These things are concerning. As a mother, you want to know who's taking care of your child," Dina said.
