Someone digging for recyclables found the /*baby in the dumpster*/, on the 600 block of 14th street, about 7:40 a.m.
Paramedics say the child appeared to be born about a month premature.
Police are looking for witnesses and are talking to people in a nearby apartment building.
Officials say the death is particularly disturbing in light of /*California's Safe Surrender Program*/, allowing parents to drop newborns off at hospitals and fire stations without facing any charges.
