LINCOLN, Neb. (AP) — State authorities have taken emergency custody of an infant whose 5-week-old sister was found dead in a Lincoln motel room.

An investigator wrote in a motion for temporary custody of the 1-year-old that the baby was pronounced dead Thursday at the Knights Inn after medics arrived. The parents told police that the child had fallen off a motel bed and then later was dropped by her father onto a bed. The parents say the tiny girl appeared to be OK, so they didn’t take her to a doctor.

The investigator says marijuana and suspected drug paraphernalia were found in the motel room. The girls, their parents and a family dog had been living in the motel for several weeks.

The baby’s parents haven’t been charged in the case.
