JERSEY CITY - The superintendent of the Jersey City building where a baby boy was found in a trash bag says he was afraid the baby was dead.

The 2-pound premature baby was found Saturday by three boys who were playing behind an apartment building on Kensington Avenue. They alerted Arturo Rivas, whose wife sprang into action to care for the baby.

It was when Rivas and his wife picked up the baby that they realized he was alive. "The baby opened his hands and my wife put her finger in the palm of his hand and he closed his finger around my wife's finger," Rivas says. "So we knew that the baby was OK, was responding."

Rivas says the baby had tissues stuck into his nose and mouth.

A Jersey City Medical Center spokesman says the baby was born about three months premature and remains in stable condition. Police are still searching for the infant’s mother.
