SAN DIEGO (AP) — His parents say the 6-year-old son of a pharmaceutical company executive has died after he fell down the stairs at his father's San Diego-area mansion, the same house where his father's girlfriend was found dead hanging nude from a balcony two days later.

Medicis Pharmaceuticals CEO Jonah Shacknai said in statement with ex-wife Dina Romano that their son Max Shacknai died at a hospital Sunday.

On Monday, Max fell down the stairs at the historic Spreckels mansion in Coronado in what police called a tragic accident.

On Wednesday, officials said Shacknai's 32-year-old girlfriend, Rebecca Nalepa, was found dead hanging nude from a balcony at the mansion.

Sheriff's investigators have not established any connection between the two deaths, and have not determined if the woman's death was a crime or suicide.
