LONDON — Tributes have been flooding in for a Japanese woman and her British husband who committed suicide following the death of their profoundly disabled son.

Friends and strangers have been inundating a Web site set up by Kazumi Puttick and her husband, Neil, with condolences. The site had been used to raise money for their quadriplegic son, Samuel, 5.

The Putticks leaped together Sunday evening off a 160-meter-high cliff on Britain's south coast. They were carrying a rucksack holding the body of their son, who died from meningitis on May 29.
