WICHITA, Kan. (AP) — The father of a Wichita baby not seen since last summer has pleaded guilty to cutting off a GPS tracking device.

The Wichita Eagle reports that 24-year-old Gary Moore Jr. entered the plea Monday. Prosecutors will recommend a 34-month prison sentence. Moore had been ordered to wear the tracking device as a condition of his probation in a 2014 battery case.

No one has been arrested or charged in the disappearance of Moore’s 5-month-old son, Vincent Moore. The child was last seen leaving a house with his father July 11. When officers stopped Moore on July 29, his 2-year-old child was with him but the baby wasn’t.

Moore has been in jail since July because of the charge and a yearlong sentence ordered served because of probation violations.
