A 20-year-old Utah woman accused of kidnapping her young son during a supervised visitation has been arrested in Washington state.

The U.S. Marshal's Service says federal agents arrested Lady Ashley Marks in Spokane on Saturday.

KUTV reports she's accused of kidnapping 15-month-old Giovanni Marks last month during a supervised visit at a home in Murray.

Investigators say the toddler's father had been awarded legal custody of the boy. The mother is in the custody of the Spokane County sheriff's office awaiting extradition back to Salt Lake County.
