The baby girl was found at Steel Lake Presbyterian Church in the 1800 block of South 308th Street, police said.

Surveillance video showed a young woman leaving the child at 2:16 a.m.

JC Gumm was the first person to find the baby when she showed up at the church about 6 hours later for band practice. As Gumm was waiting for someone inside the church to let her in, she heard what sounded like a baby cooing.

"I came over here and I looked. I saw a towel and there was a baby right here. I said 'oh no' the baby needs help," Gumm said.

Gumm dialed 911.

"I picked it up…and said ‘It's alright little one, the paramedics are coming,'" Gumm said.

Police arrived at the scene around 7:55 a.m., the Federal Way Police Department said.

Nurses at St. Joseph Medical Center in Tacoma have named the infant Autumn Doe, instead of the traditional Jane Doe, said hospital representative Gale Robinette. The infant weight 5 pounds and is in very good shape with no signs of injury, Robinette said.

Police said the case is being investigated as abandonment of a dependant person, a felony. Police said it is not illegal to leave a newborn child at a church or other public location, but a child must be turned over to a qualified person.

Just six years ago, our state enacted the Newborn Safety Act which allows mothers to legally abandon healthy infants, less than 72 hours old. The baby can be left at a fire station or hospital, but must be left with a person and not just at a building.

Anyone with information about the case is asked to call 911 or Federal Way police Detective KC Krusey at 253-835-6895.
