The funeral Saturday at St. Joseph's Church in Spring Valley was paid for by donations that poured in from around the state.
Authorities say 'Baby Angel', as the infant is now being called, was born alive, then murdered and left in a dumpster in Spring Valley.
Police are still searching for the baby's mother.
They have released pictures of a floral towel and black skirt found with the body.
There is a reward of $5,000 for information leading to the mother.
