A Washington state mother has been arrested after her 7-month-old daughter was found dead, left home alone with a “severely malnourished” toddler in Yakima.

Yakima Police said they conducted a welfare check on the apartment just before 7:30 a.m. on Tuesday after an unidenfied woman called 911 and said there was a possibly dead baby inside, the Yakima Herald-Republic reported. The caller said she was leaving to kill herself.

Officers found the children after hearing a child crying inside.

The baby was found dead in a bassinet, and an autopsy revealed she died from dehydration.

The 2-year-old girl was taken to a hospital, where doctors found evidence of malnourishment and neglect.

The mother was found at Squaw Rock RV Resort & Campground, where she had allegedly driven and then run out of gas, the Tri-City Herald reported. Police said they found her vehicle with a note on it about the gas.

Kyleah Rose Tolle, 20, was charged with manslaughter, criminal mistreatment, and family abandonment, the Herald-Republic said.

She is being held on a $20,000 bail in the cases involving her children, plus a $5,000 bail on a 2023 case in which she was accused of starving two dogs, killing one of them.
