SAN JOSE — As fire investigators probe for what sparked a fast-moving blaze Sunday that consumed three homes in South San Jose, an outpouring of support headlined by the San Jose Earthquakes has surfaced to help a displaced family and an associated youth soccer team that saw its resources also go up in flames.

Rigo Rangel lost the home he shared with his wife and three children. That included the destruction of equipment, cash and nearly a decade of trophies and other keepsakes related to the Fuerza team of the NorCal Premier Soccer League for which he volunteers as coach. The boys’ 17-and-under squad includes his 16-year-old son Tony.

When news of the soccer loss proliferated in local media, it caught the attention of the Earthquakes organization, which pledged to donate $5,000 to recoup more than $3,000 in league fees collected from players’ families and help the youth team replace some of the destroyed gear.

“We read a story online about the house fire, and we want to be a community-focused, community-oriented organization,” said Jed Mettee, the team’s vice president of marketing and communications. “We saw an opportunity to help this group of kids and were happy to contribute.”

Much of the Earthquakes’ donation will go toward field rentals and other administrative costs, and Fuerza assistant coach Richard Johnson has helped formed a GoFundMe account to help the Rangel family and to replace soccer balls, goals, cones, hurdles, training poles and parachutes used for agility and speed exercises.

Johnson said he was “pleasantly surprised” by the swift support from the Earthquakes and other local residents.

“He wasn’t looking for donations, but I know Rigo and his family greatly appreciate it,” he said. “No matter how bad things are, people always step up because it’s the right thing to do.”

Meanwhile, the San Jose Fire Department has launched a “full investigation” into the three-alarm fire Sunday afternoon that destroyed three homes and damaged two others on Snow Drive south of Hellyer County Park, fire Capt. Peter Caponio said. Burning embers cleared the sound wall along adjacent Highway 101 and sparked a brush fire along the freeway.

And despite it all, soccer practice for Fuerza will continue as it always does on Tuesday and Thursday evenings at Watson Park, even if Tony Rangel has to don a borrowed jersey and cleats for the time being. Johnson is also confident they’ll play in a tournament in Cupertino in two weeks.
