Destruction is seen in the aftermath of a gas line explosion September 10, 2010 in San Bruno, California. The explosion rocked a neighborhood near San Francisco International Airport, destroying 37 homes, killing at least 4 people, and injuring at least 50.
A state forensics team has identified three more victims in the San Bruno pipeline explosion, bringing the number of dead to seven.
The San Mateo County Coroner says an 85-year-old woman, her 50-year-old son and her 17-year-old grandson died in the explosion and fire. Investigators found their remains inside a house in San Bruno’s Glenview neighborhood.
A forensics team from the California Department of Justice’s missing person unit used DNA to identify the victims.
Investigators identified four other victims soon after the blast two weeks ago.
A local burn center is treating four more people who were injured in the blast and the fire. A hospital spokeswoman said three of them are in critical condition.
The fire touched off by the blast destroyed nearly 40 homes.
The National Transportation Safety Board’s investigation into what caused the natural gas pipeline to rupture could take more than a year. But the board could issue preliminary findings within a month.
