Motwani death: No foul play suspected

There is no initial evidence of foul play in the drowning mishap, Atherton police Sgt Tim Lynch said.

Lynch said an autopsy report is awaited to carry forward the probe into the incident.

"We're kind of in limbo... It could have been a simple accident or many other things," he added.

Motwani (47) was found dead in the backyard swimming pool of his Palo Alto home in California on Friday.

Local media reported that Motwani, who did not know how to swim, may have slipped into the pool and drowned. Paramedics were summoned when his body was found.

Lynch said firefighters and a police officer pulled his body from the bottom of the pool.

Motwani's death sent shock waves across the Silicon Valley and the tech world globally, as he was the master brain behind several key advancements in the world of Internet, including Google and PayPal.
