SPANAWAY, Wash. -

Pierce County sheriff's detectives are investigating the death of a Spanaway 2-year-old who had a fatal amount of methamphetamine in his system.

The Pierce County medical examiner's office said Tuesday that Nathan Iverson died Dec. 6 of acute methamphetamine toxicity. Emergency crews took him from a house to Mary Bridge Children's Hospital in Tacoma where he died.

Spokesman Ed Troyer told The News Tribune the house is well-known to deputies.

Residents admitted they used drugs but there were no signs of drugs when deputies arrived.

Troyer said, "The bottom line is, one way or another, this kid ingested enough meth to kill him."
