He was on a train to Sendai when the 8.9 magnitude earthquake struck there.
"We just manned the phones. We had five to six cell phones going, three computers and just calling embassies, Red Cross, Japanese emergency service," Judy said.
That was Friday.
Relatives in Japan had heard Ken was taken off the train and taken to a refugee camp.
"You just can't describe it. You go to a minute of a high to hours of lows," Judy said.
One of those highs was when the family got an email from a Blackberry in Japan saying Ken was safe and sound. Still time went by and they had not spoken to him by phone.
They could only watch the nuclear threat and horror unfold on TV.
"It's very surreal and I know people used that term a lot, but I didn't know what the word meant until now," Ken's aunt Rose Tukeva said.
Finally, after days of exhaustive phone calls and Facebook emails, the family tracked down Ken.
"He said, 'Mom I was in the thick of it,'" Judy said.
The phone call was brief.
But the news was a relief unlike any they've experienced.
"We are very excited for my son, but we're still hurting for Japan," Judy said.
Ken Seagreaves' father and grandmother also went to Japan on a different flight. They landed in northern Japan and the family quickly got in contact with them. They are also safe and sound.
