LAS VEGAS (AP) — A 35-year-old Las Vegas man is behind bars in the death of his girlfriend’s child.

Las Vegas police say Cory Terrell Simmons has been arrested on suspicion of murder by child abuse after the toddler died just before midnight Thursday.

Police say they responded to reports of a child in medical distress about 10:30 p.m. Thursday at a residence in northeast Las Vegas. The toddler was taken to University Medical Center’s pediatric trauma center and pronounced dead.

Investigators say Simmons was the only caregiver home at the time of the incident. Two other children were asleep in the home and are now in Child Protective Services custody.

The child’s name has not yet been released.
