K-9 units and a chopper are being used to search the area for the inmate who escaped from custody in downtown Little Rock.
Castro had been jailed since May 2013 after being accused of three counts of rape involving a child under the age of 14.
Castro is 5'1" tall and weighs about 118 pounds.
The Pulaski County Sheriff's Office reports Castro escaped from a transport vehicle while being taken to the courthouse downtown around 8 a.m. Monday.
