TACOMA, Wash. (AP) -- Tacoma police say they'll keep digging for the body of a 3-year-old boy who disappeared 28 years ago.
Officers dug pits and sifted dirt Tuesday but found only rocks.
Spokesman Mark Fulghum told The News Tribune it's a slow, tedious process.
Cold case detectives were directed to the site along Ruston Way by the father of Wallace Guidroz. The 54-year-old Stanley Guidroz is jailed in Houma, La., for investigation in the death of his wife.
In 1983 he said his son disappeared while playing in Point Defiance Park.
No charges have been filed in the disappearance.
