You get down in that hole there boy and I don't want to see any attitude...

...or maybe we'll arrange a little visit by the I.N.S.

DIAMOND BAR -- A man killed when a trench he was working in collapsed on him was identified Wednesday by a Los Angeles County Coroner's official as Salvador Blanco Orozco, 22, of Hacienda Heights.

Orozco was working in the trench Monday at a housing development in Diamond Bar when he was trapped in the cave-in, Los Angeles County Fire officials said.

The roughly 13-foot-deep trench was dug to house a retaining wall, but the dirt was not properly shored up by wooden supports, said Susan Gard, a spokeswoman for the California Health and Occupational Safety Administration.

Cal-OSHA and the Los Angeles County District Attorney's office is investigating the death, Gard said.

A and C Construction, which hired Orozco, did not have the proper permit to dig the trench, she said.

"It seems like the sheriff's department is interested in pursuing it criminally,' she said.

About time.
