GoFundMe for twin wrestlers killed in house fire

A GoFundMe page has been established for twin girls -- both middle-school wrestlers -- who were killed in a house fire outside San Francisco last weekend.

The fundraising website is intended to help pay for funerals for Trinh and Tram Tran, 14, and their mother, Mau Dao Tran, all who died in the fire in their home in Vallejo, Calif. about 3 a.m. last Sunday. Funds are also intended to assist a fourth member of the family, Vy Tran, eleven-year-old sister of the twins who survived the fire and is recovering from her injuries, as well as the family's father, Tuan Tran.

Both Trinh and Tram had wrestled at Hogan Middle School in Vallejo, where they made many friends.

Their wrestling coach, Jason Guiducci, described each of the Tran twins to local TV station KPIX .

"Trinh was the soft-spoken but strong silent type, Tram was the bubbly, uplifting type," Guiducci told the CBS affiliate serving the San Francisco Bay area. "But you knew that they loved everyone here and everyone loved them in return, there was no way you couldn't love those kids."

A video tribute to Trinh and Tram Tran -- including many images of the twins in action as wrestlers -- is available for viewing online.

According to Vallejo Police, officers smelled smoke while on routine patrol. They found the Tran home engulfed in flames, family members still inside.

On Wednesday, Vallejo Police announced they are investigating the fire as a homicide. No suspects have been named, and no arrests made.
