WICHITA, Kan. (AP) — A Wichita couple who left their baby in an apartment closet while the mother drove the father to work have appeared in court on charges of misdemeanor child endangerment.

The Wichita Eagle reports a judge entered not guilty pleas Wednesday for 18-year-old Destiny Lee and 19-year-old Donivan Turner. Preliminary hearings for both are scheduled Aug. 13.

A maintenance worker repairing an air conditioner found the 1-year-old boy May 6 inside a closet in the couple’s apartment. Police said at the time the temperature in the closet was about 90 degrees. The baby had been there about 20 minutes.

The mother told officers she had been putting the sleeping boy on a mattress inside the closet for about two months while she took the father to work.
