A 20-year-old man has been charged with sexual misconduct with a minor for allegedly impregnating a 15-year-old girl with their second child together.

William Davis, 20, was charged with one count of sexual misconduct with a minor in August 2018.

The investigation began in January 2018 when the Department of Child Services received a report a minor, 15-years-old at the time, was pregnant. She has since turned 16.

The Special Victims Unit investigator learned a similar investigation was conducted in January 2017 when the same girl was 14-years-old and pregnant with Davis' child, according to the probable cause affidavit.

During the January 2017 investigation, Davis said he didn't know the girl was 14.

Both Davis and the teen told investigators they haven't had sex since before their first child was born, reports said.

After the second child was born, in March 2018, a DNA sample was obtained.

The results indicated there was a 99.9999-percent chance Davis was the father of the second child, according to the probable cause affidavit.

Davis and the teen spoke with investigators again. They each provided different cities where they may have been intimate around the conception date, according to reports.

Davis is being held at the St. Joseph County Jail on $500 bond. He is due in court September 17.
