Authorities expect to know Friday whether a child's body found in an undeveloped housing tract belongs to a 10-year-old Las Vegas girl who has been missing for a week.

Las Vegas police homicide Capt. Chris Jones says investigators didn't immediately know if the body discovered Thursday is that of Jade Morris. But he says there's a "likelihood" that it's her.

Police say Jade was last seen by her family at about 5 p.m. Dec. 21 with Brenda Stokes. Stokes was arrested later that night after she was accused of slashing a co-worker with razor blades at the Bellagio resort casino.

Stokes is scheduled to make a court appearance in that case Friday morning.

Jones says Stokes hasn't cooperated in the investigation about the girl's whereabouts.
