SIOUX FALLS, S.D. (AP) — A woman charged with child abuse for leaving her 2-month-old baby outside a Sioux Falls church overnight has been sentenced to 90 days in jail.

Mary Louise Jennesse, 29, pleaded guilty to abuse or cruelty to a minor under 7 as part of a plea deal. She also was sentenced Monday to three years' supervised probation that could lead to up to 10 years in prison if broken, the Argus Leader reported .

Jennesse and Ronald Harrison, 39, were charged after the baby was found cold and wet in a car seat outside a church in October 2017.

Harrison pleaded guilty to a child abuse charge in March. He was sentenced to 180 days in jail and 10 years' suspended supervised release.

The couple told police they had an argument and thought the other would grab the baby.

Harrison told investigators they were smoking drugs at the church where they left the infant, according to court documents. Jennesse told police she and Harrison had smoked synthetic marijuana that night, court records show.

"This is a particularly troubling case," said Second Circuit Court Judge Natalie Damgaard. "The child was found very cold, very wet. We're very lucky the child (is doing OK)."

Jennesse said at the sentencing that addiction has troubled her most of her life, and that the incident has changed her "for the better."
