Authorities say the body of an Arkansas real estate agent who disappeared Thursday has been found in a shallow grave at a concrete company.

Pulaski County Sheriff's Office Lt. Carl Minden says Beverly Carter's body was found early Tuesday at Argos Concrete Company in a rural area about 25 miles northeast of Little Rock.

The 49-year-old Carter had planned to show a house Thursday night in Scott, a rural area east of Little Rock, but she never returned from the appointment.

Police arrested 33-year-old Arron Michael Lewis on Monday after he had been named in an arrest warrant on suspicion of kidnapping. Minden says charges will be upgraded to capital murder.
