Muni train kills man at Civic Center Station SAN FRANCISCO

A man in a wheelchair was killed Monday when he fell onto the tracks at Muni Metro's Civic Center Station and was run over by a train, officials said.

The train apparently severed the leg of the man, described as being in his 50s or 60s, said Paul Rose, a Muni spokesman. The victim died at a hospital, Rose said.

The medical examiner's office said the man's name was being withheld while authorities tried to locate his relatives.

Emergency crews arrived at the station around 11:26 a.m. after callers said someone had been struck on the westbound tracks, said Mindy Talmadge, a Fire Department spokeswoman.

"How they got (on the tracks), we don't know," she said. "They could have fallen, they could have jumped."

Witnesses, however, said it appeared the man had fallen accidentally.

About 40 passengers remained onboard while rescuers pulled the victim out from under the train.
