(CNN) -- Facebook's Mark Zuckerberg and his wife were the second-biggest charitable donors in the United States last year, appearing behind only billionaire Warren Buffett on a list of the nation's most generous philanthropists.
Zuckerberg, along with wife Priscilla Chan, gave roughly half a billion dollars ($498.8 million) to the Silicon Valley Community Foundation, according to The Chronicle of Philanthropy.
The group released its annual Philanthropy 50 over the weekend.
The Facebook founder and CEO was one of three tech-industry titans in the list's top five.
BIG BEAR, Calif. (AP) — The man believed to be fugitive ex-cop Christopher Dorner never came out of a California mountain cabin, and a single shot was heard inside before the cabin was engulfed in flames, a law enforcement official told The Associated Press.
The law enforcement official requested anonymity because of the ongoing investigation.
A fourth person — a deputy — died earlier in the latest confrontation with America’s most-wanted man, which seemed to be coming to an end.
Officials were waiting for the fire to burn out before approaching the ruins to search for a body.
“We have reason to believe that it is him,†San Bernardino County sheriff’s spokeswoman Cynthia Bachman said.
The cabin was on fire and smoke was coming from the structure in the late afternoon after police surrounded it in the snow-covered woods of Big Bear, a resort town about 80 miles east of Los Angeles.
