"It's so important to get the support from Cathy. It's just a great thing," Manny said.
He said in 2008, walkers raised $147,000 for the Community Hospice.
Kai's Crew consists of many of Kai's family members, including his parents and extended family. Pettigrew's partner, John Ibes, is part of the crew, and her stepdaughter, Jolie, normally makes the trek from New York City to walk in the event, but was in London this year.
Pettigrew said her stepdaughter still wanted to be a part of the event, even if she could not make it to walk, and pledged to raise money while overseas. Pettigrew was thankful, and shocked when she heard her stepdaughter pulled in $5,000 all by herself.
Pettigrew said she has a network of people at her office in the Supreme Court Appellate Division in Albany, and was able to raise $900 there. She also seeks donations from other family and friends as well.
Pettigrew has no plans to stop anytime soon she said, and has hopes others will keep Kai's legacy alive.
"I'm going to do this until I can't do it anymore," she said. "And I hope my kids carry it on."
Pettigrew said she is confident that Kai walks with them, and watches "with a smile from heaven."
