A 2-year-old boy weighing less than 10 pounds was found in his Moses Lake home in a case that one investigator called the “worst case of child abuse or neglect he has ever seen.”

The toddler is on life support at Providence-Sacred Heart Medical Center in Spokane, authorities said.

Grant County sheriff’s deputies were called to the boy’s home around 1 p.m. Wednesday along paramedics and EMTs from Grant Fire District 5 and AMR. When they got there, they found the boy, who appeared extremely malnourished, with no heartbeat, said Kyle Foreman, a Grant County spokesman.
