A Sioux Falls woman and a 17-year-old man were arrested Friday for assaulting a newborn infant, police said.
Aubrey Lynn Heck, 20, and the teenager face felony child abuse charges for repeatedly striking the one-day-old infant.
The incident unfolded about 9 p.m. at an apartment after the teenager reportedly stepped on the infant's face while trying to move a relative off the couch, police said.
"The infant's mom yelled at him not to step on the child and he ended up slapping the infant in the face," police spokesman Sam Clemens said.
The infant's mother left the room with the baby, but Heck and the teenager followed.
Heck then stepped on the infant's feet while he was in his carrier "causing him to scream."
The act was intentional, Clemens said.
The infant's mother yelled to stop stepping on her child. The 17-year-old then "grabbed her by the head and started slamming her into the wall," Clemens said.
Heck broke up the assault, and the mother fled with the infant to a nearby home to seek shelter, police said.
The teen was later seen assaulting Heck and police were called.
The 17-year-old, who was intoxicated and fled from officer when they arrived, was arrested on charges of abuse or cruelty to a minor under seven, underage consumption, simple assault, resisting arrest, obstruction, fleeing police and false impersonation.
Heck was charged with abuse or cruelty to a minor under the age of sever and underage consumption.
Clemens said they found bruising to the ankles of the infant.
Heck made her initial appearance in court Monday. The 17-year-old made his appearance in juvenile court.
Abby Roesler, Deputy Minnehaha County States Attorney, told the court that given the seriousness of the allegation and Heck's history of underage consumption and missing court that $2,500 cash or surety bond was appropriate. Roesler said Heck's blood alcohol level was three time the legal limit to drive when she was arrested.
Judge John Hinrichs released Heck on a personal recognizance bond. But not before explaining to her the magnitude of the crime and strict conditions of her bond.
"I'd wipe the smirk off your face," he said. "You need to get yourself in the right frame of mind right now."
