The death of Jonah Shacknai's girlfriend, Rebecca Zahau, who was found nude and hanging from an outside balcony at the Coronado mansion of her boyfriend, will be ruled a suicide, RadarOnline.com is exclusively reporting.
Zahau's death came just two days after Jonah's six year old son, Max, was found unconscious at the base of the stairs. Max died several days later in hospital. Rebecca was babysitting Max at the time.
The San Diego Sheriff's Department will formally announce their findings on Friday morning.
A source close to the situation tells RadarOnline.com: "Rebecca killed herself. That is what the investigation determined. There was no foul play, and the evidence is ironclad that Rebecca killed herself."
Max Shacknai, most likely, slid down the bannister of the staircase, head first, at his dad's mansion and hit his head, our source says.
The San Diego Medical Examiners Office and the Coronado Police Department will also be at the press conference on Friday.
