DES MOINES, Iowa (AP) -- A Des Moines man accused of sexually abusing three of his nine children has been captured in Chicago.

The U.S. Marshals Service says the 36-year-old man was taken into custody Thursday morning at an apartment complex where authorities believed his mother lives.

Officials searched an apartment and learned the man fled out a back door. Officers found him hiding under a stairwell.

The man faces eight counts of sexual abuse. His wife, who was arrested in Des Moines on Monday, faces three counts of neglect.

A nationwide hunt for the man ranged as far away as Salt Lake City, where his van was found last week at a bus station.

The Associated Press is not using the couple's names to protect the privacy of the children.
