She was found dead Labor Day afternoon by a passing boater

The newborn girl was dumped in the Mississippi River on or just before Labor Day, sealed in a canvas bag with the name of a Mexican tourist town stitched on the side.
Inside, she was wrapped in a green T-shirt, and tied in two plastic garbage bags. Two small angel figurines lay next to her.
A charm bracelet - with an eye motif - and two more, larger angel figurines were placed in the canvas bag, too.
Then someone - presumably her mother - put the 7-pound girl in the river near Winona. She was found dead Labor Day afternoon by a passing boater.
"We've named her Angel," said Winona County Sheriff Steve Brand. "We want to give Angel a last name."
The new details about the fourth newborn to be pulled dead from the Mississippi River in southeast Minnesota since 1999 were released today at a press conference behind the courthouse in downtown Winona.
Investigators from the county and the Minnesota Bureau of Criminal Apprehension have tracked down about 25 leads in the case, but none have panned out. That's why Brand and BCA Senior Special Agent Drew Evans made a public plea for the mother to come forward. They hoped that the items found in the bag with Angel would help someone identify the mother.
Evans said investigators want to find the mother, who they believe gave birth alone without medical attention, because she likely needs physical and mental help.
