Autopsy reports have revealed how an ex-Meta engineer murdered his twins last year in their $2.1 million family home before turning the gun on himself.
Anand Sujith Henry, 37, killed his sons Noah and Neithan, both four and his wife, Alice Benziger, 38, at their ritzy San Mateo house in February 2024.
Responding officials found the couple with gunshot wounds beside a 9mm pistol and a loaded magazine in the bathroom.
The bodies of the boys was found on a couch inside one of the five bedrooms.
In a newly released coroner's report, San Mateo officials have discovered the children were killed in a homicide.
Reports suggest that the boys were found in a supine position, with a pillow resting along each of their right sides which indicated that they were smothered to death.
Officials also noted a large 'foam cone' emerging from Noah's nose and mouth at the scene and small red or purple dots on the boys' faces - signs of strangulation or choking.
Examiners explained that that the dots and the pillows 'suggests the possibility of smothering, however this diagnosis cannot be made based on the limited investigative information and nonspecific findings', according to the Sacramento Bee.

Henry, a former Software Engineering Manager at both Meta and Google, filed for divorce in December 2016, records show - years before Benziger, a data science manager at Zillow, gave birth.
Apparently, the divorce never materialized, and after leaving his post at Meta this past June, Henry founded his own AI company.
The firm, identified on the seasoned computer scientist's social media as Logits, provides enterprises with the means to 'privately train and serve Generative AI models' to serve their own specific business needs. Its site, as of writing, is down.
Before that, he worked at Meta for a year and a half, after a nearly eight-year stint at Google's office in Sunnyvale.
At one point, Henry lived in New York City, where he was a member of Toastmasters, a non-profit that teaches how overcome a fear of public speaking.
During that time, the family lived in at least four apartments across San Francisco, records show before relocating to the home where the crime occurred.
This move happened around the time of the birth of his children - and local police revealed that in the time since, they have been called to the home several times.
They did not disclose the nature of those calls, and said there was no note left at the scene.

Benziger's mother had reportedly been staying with the family, leaving on February 11 - the day before the murder suicide.
Neighbors said that they have never seen anything like this in their community.
Ashley Villalobos, 27, who worked as a nanny for the twins two years ago, shared her own shock at the news and how she'd never seen any red flags with the couple.
'My heart aches that their lives were taken in such an unforeseeable incident,' she wrote in a social media posting.
'I can't wrap my head around how or why. All I have is the memories and silly beautiful moments I got to share with these boys.
'Every morning they loved to play with bubbles in the front yard while we waited for the morning bus to pass by on Alameda so they could wave hi! It was always a highlight of their morning.
'Anand would come into the room while Alice wrapped up her work stuff,' Villalobos continued.

'He would say to the boys with a big smile excited to see the boys 'alright boys time to play with papa!' They jumped with joy happy to play with dad.
'Alice loved those boys sooo much,' she wrote. 'I can't come to understand what went wrong…. You just never truly know.'
The couple, family said, were both alumni of TKM Engineering College, and also both attended Carnegie Mellon University in Pittsburgh.
After that, Alice obtained a Master's in data science at the University of San Francisco, her LinkedIn shows, after which she held positions at Dictionary.com, Idibon, and Change.org, before assuming her senior role at Zillow six years ago.
The couple emigrated to the US in 2018. Henry's father, Dr G. Henry was the former principal of Fatima Mata National College in Kerala, India.
