DES ARC, Ark. (CBS NEWS) -- Police in two states say they are trying to figure out why a couple hauled an elderly man’s body in a suitcase more than 1,000 miles from upstate New York to Arkansas.

Virginia Colvin and Michael Stivers are charged with abuse of a corpse after the two allegedly drove 19 hours in a pickup truck from Johnstown, New York to Des Arc, Arkansas, where police say they dumped the elderly man’s body in a rice field, reports the Northwest Arkansas Democrat Gazette.

Police think the man, who was believed to be around 90, died of natural causes sometime last week. The couple were living with the man in a Johnstown, New York home and acting as his caregivers, according to the paper and CBS affiliate WRGB.

Police say the body found Sunday at a farm 50 miles northeast of Little Rock appears to be that of the man who died in Johnstown. The body has been sent to an Arkansas crime lab to be identified and to pinpoint how he died.
