Number of Victims in Calif. Gas Line Blast Unclear

SAN BRUNO, Calif. (AP) — Authorities in California are trying to identify remains they found in the wreckage of a natural gas line explosion.

San Mateo County Coroner Robert Foucrault (FOW-crowlt) says Sunday the official death toll remains at four. Authorities had said Saturday that seven people had died. But they later said that while some remains had been found, it wasn't immediately clear if they were from victims already accounted for.

Foucrault says they're still trying to confirm whether the remains are human and identify victims. Police have said five people are missing.
