CRAWFORD COUNTY, AR — A fourth suspect is in custody in connection with the death of a Kansas couple at the Barton County Fair in Great Bend.

Just after 3:30p.m. Thursday, police arrested 37-year-old Christine Marie Tenney  of Sante Fe, Texas, according to Detective Jonathan Wear.

Tenney is being charged with Abuse of a Corpse, Felony Theft by Receiving, Tampering with Physical Evidence, and Obstruction of Governmental Operations.  She was booked into the Crawford County Detention Center with no bond, according to Wear.

Three other suspects, Michael Fowler, Rusty Frazier and Kimberly Younger, also known as Myrna Khan are also jailed for the alleged murder of fair vendors Sonny and Pauline Carpenter of Wichita. Authorities believe the Carpenters were killed July 13, after meeting the carnival workers as the couple sold crafts, jewelry, purses and other handmade items during the fair, according to Wear.

Their bodies were found days later in a shallow grave in a forest near Van Buren, Arkansas.
