Alexander Jentzsch was found dead inside his in-laws's Sylmar home on July 3, but it was hours before anyone called 911.
The coroner's office said Jentzsch's in-laws saw him asleep in his bed around 9 a.m. on Monday, July 2. Twelve hours later, around 9 p.m., he had not moved, but no one checked on him.
The next morning, his father-in-law did check and found Jentzsch unresponsive. The father-in-law took a child to school, and when he returned home, he finally called 911.
"In this particular case, there was some information that we received that we are looking into, along with the fact that we've had other family members provide information or question his death," said Los Angeles County Assistant Coroner Ed Winter.
No one at the in-law's home would talk to Eyewitness News about Jentzsch's death. The 27-year-old's father is Heber Jentzsch, the president of the Church of Scientology International. Heber Jentzsch hasn't been seen in public for years, but at the height of his influence in the church, he was often seen in company of high profile church members, such as John Travolta.
Alexander Jentzsch's mother, Karen de la Carriere, left the church and said her son then disconnected from her. "Disconnected" is a term Scientologists use to describe the decision to cut themselves off from loved ones who leave the church. She said when her son died, she wasn't allowed to see his body and has many questions about his death.
"Why give the coroner smoke and mirrors, and blame it all on Alexander? 'He was drinking, he has a history of self-medicating, he did this, he did that.' Oh come on, it smells to high heaven," said De la Carriere.
The coroner's office said an autopsy has been completed, but investigators are awaiting toxicology results before determining a cause of death.
