J.R. Stone anchors KRON 4 NEWS AT 8, KRON 4 NEWS AT 10, and SPORTS NIGHT LIVE on both Saturday and Sunday. He reports for KRON 4 NEWS AT 10 during the week.

Stone has 17 years of news experience and recently anchored KRON’s Emmy winning breaking news coverage of the Ghost Ship warehouse fire in Oakland that killed 36 people. He anchored KRON’s breaking news coverage of the Oroville Dam Crisis that forced thousands of people to evacuate. When the Asiana Airlines flight crashed at SFO in 2013; J.R. anchored for 10 hours.

When news stories aren’t breaking sports stories usually are. J.R. has covered 2 World Series, 3 Super Bowls, 3 NBA Finals, and a Stanley Cup Finals. When the Giants won their last two World Series; he was in the clubhouse interviewing players and getting doused with champagne as he did so. He’s a sports junkie and while he does love covering Bay Area teams, he won’t hide the fact that he’s a huge Chicago Bears and Michigan Football fan.

“I haven’t met you but I feel like you’re the kind of guy I could be friends with” is something that a viewer told J.R. at a San Jose Sharks game recently. Stone prides himself as being a journalist of the people and took that comment to heart. Most of the stories J.R. breaks come from viewers. He does at least 4 hours of Facebook Live with many of those KRON viewers every weekend. Conversations on Facebook Live range from breaking news stories to what’s for dinner.

As a reporter J.R. doesn’t beat around the bush. He’s exposed rat problems at San Francisco Walgreens stores, helped bust apartment owners who discriminated against African Americans, and recently exposed teen riots that broke out at an Oakland carnival.

Before coming to the Bay Area J.R. was a journalist in Florida, Oklahoma, and Arkansas. He’s done live segments for CNN, The Weather Channel, and the CBS Early Show. If you have a comment, story idea, or just want to say hi you can find him at KRON 4 J.R. Stone on Facebook.

When finding out he’s from Hawaii, the first question people in the Bay Area ask Mark is ‘why would you ever leave that paradise?’

For most, it’s difficult to accept any answer. But for him, it’s simple.

Great opportunity is a mix of hard work and perfect timing, and life on the other side of the Pacific Ocean is one that Mark couldn’t pass up.

Born and raised in Honolulu, Mark dreamed of having a career in sports, but his love for writing helped him realize early on that he wanted to be the one covering the games, not playing them.

Mark discovered his passion for journalism in high school, he got his degree in Journalism from Hawaii Pacific University, then spent the next four years diving into his craft at Hawaii News Now (Hawaii’s CBS/NBC affiliate).

At HNN, Mark gained experience in a newsroom from a variety of positions, including associate producer, weekend assignment editor, one-man band reporter, to eventually, main sports anchor.

Leaving home is always hard, yet for Mark, being immersed in championship teams and a sporting culture that’s as booming as the tech industry makes the transition from island paradise to sports paradise a little easier.
