She was charged with first-degree murder, second-degree murder and first-degree manslaughter, police said.

The cold case first heated up 10 years ago as DNA technology advanced and investigators looked into obtaining DNA from the unidentified baby, Webb said.
In 2009 the baby's body was exhumed and his DNA was put into databases, but over the years there were no matches, Webb said.

A possible match was found in February 2019. The suspect, Bentaas, still lived in Sioux Falls and police executed a search warrant to get her DNA, police said. DNA tests then confirmed Bentaas was the baby's mother, police said.
The baby's father was also still living in Sioux Falls, Webb said.
"We did interview them last Wednesday on the anniversary that we believe the baby was put in the ditch, on Feb. 27," Webb said. "It was confirmed that the baby was theirs."
Bentaas is scheduled to appear in court on March 11. Her public defender declined to comment to ABC News Friday.
