Baby of killed pregnant traffic agent dies

? An infant boy delivered prematurely after his traffic agent mother was struck by a van and pinned under a bus has died, authorities said Friday.

Sean Michael Justin Sanz had been in intensive care since he was delivered by Caesarean section shortly after a runaway van hit his mother on Aug. 14. He weighed 3 pounds, 6 ounces at birth.

His mother, traffic agent Donnette Sanz, survived the delivery but died about an hour later in an emergency operating room. She was seven months pregnant.

The van, driven by a 72-year-old man with what authorities say is a long history of driving offenses, hit Sanz when she was crossing a Bronx street on her lunch break. The impact sent her flying into the path of a yellow school bus, which ran her over. About 30 bystanders helped hoist the 5-ton bus from her body in a rescue that made the front pages of the city’s tabloid newspapers.
