Charges of abuse and neglect have been filed against a father after his baby boy was found cold and wet outside of a church after being left outside for 18 hours Monday afternoon into Tuesday morning.

Ronald Terry Harrison, 38, faces felony and misdemeanor charges of child abuse and contributing to the neglect of a minor, Minnehaha County State's Attorney Aaron McGowan confirmed Thursday morning. He is being held on a $10,000 cash bond. The mother has not been charged.

Police say Harrison and the boy's mother were arguing Monday around 2:30 p.m. outside Faith Family Church at Eighth Street and Spring Avenue when the baby was left alone.

Parents told police it was an accident, police spokesman Sam Clemens said. The parents reported the baby missing at 9:30 a.m. Tuesday. The baby had been found by a church worker at 8:30 a.m. near a door that is only open to employees during the week.

The parents told police when they reported the baby missing that they had "accidentally lost," "forgot," or "misplaced," the child near Eighth Street and Spring Avenue, according to court documents.

Harrison and the boy's mother had their 2-and-a-half month boy and 1-year-old girl with them during the argument. The woman started to leave, Clemens said, and the 1-year-old girl left in another direction.

Harrison went to get the 1-year-old, but nobody grabbed the baby. Clemens said both parents assumed the other one had the child. Security video shows Harrison back in the area with the 1-year-old around 2:50 p.m. and not returning for the baby.

"Nobody went back to check," Clemens said.

During an interview with a detective, according to the affidavit, Harrison said the child's mother had left and he ran after his 1-year-old daughter. When he came back, he saw no one at the church. He walked to the mother's house about three blocks away and knocked on the door. When no one answered he said, "It's raining out. I"m not gonna stand out here in the rain." He went home and didn't hear from the child's mother until the next morning and then went to the police station.

The 2-month-old boy is doing well. An administrative assistant with the church gave the boy a bath and changed his diaper.

"He was out there, out in the cold, with no blanket, soaking wet," said Adrienne Horsley. "He was wide awake looking at me. I'm thankful he was alive."

The baby was "fairly wet and cold," said police Capt. Loren McManus on Wednesday.

The National Weather Service said the Sioux Falls area had heavy rain on Monday night, with a low of 53. The NWS put the Sioux Falls metro area in a flash flood warning between 1 and 2 a.m. on Tuesday. The child was put in an area with no overhead protection.

Clemens said the baby remains under protective custody. He didn't know why the state's attorney's office charged the father but not the mother.

Harrison has multiple former driving under the influence, driving with a revoked license and drug possession charges, according to a background check.
