A popular Stanford University professor who drowned last month in his backyard swimming pool had a high blood alcohol level, according to the San Mateo County Coroner's office.
Toxicology results showed Motwani's blood-alcohol content was .26, more than three times the legal limit for driving.
Motwani was last seen June 5 during a party at his home, according to the coroner's office. Friends of Motwani said he did not know how to swim.
The 47-year-old computer science professor was renowned for his academic research and for mentoring the founders of Silicon Valley startups, including Google's Sergey Brin and Larry Page. He was born in Jammu, India, and earned a bachelor's degree in computer science from the Indian Institute of Technology Kanpur in 1983 and his Ph.D from the University of California at Berkeley, in 1988.
Motwani left behind his wife, Asha Jadeja, two daughters, Naitri and Anya, and two brothers.
