Former "MythBusters" co-host Adam Savage said on Twitter, "I'm at a loss. No words. I've been part of two big families with Grant Imahara over the last 22 years. Grant was a truly brilliant engineer, artist and performer, but also just such a generous, easygoing, and gentle PERSON. Working with Grant was so much fun. I'll miss my friend."
"Heartbroken and in shock tonight. We were just talking on the phone. This isn't real," Kari Byron, his other co-host, wrote in a tweet.
