The nuns' bodies were discovered by a Durant police officer performing a wellness check after they didn't show up for work in the morning, Assistant Police Chief James Lee said. Durant is a small rural town, about 95km north of the capital, Jackson.
On Friday, police said there was evidence of a break-in at the home the nuns shared and that a blue Toyota Corolla that belonged to them was missing. Later that evening, the missing Corolla was discovered abandoned on a street less than 1.5km from where the nuns were found dead, AP reported.
The Catholic Diocese of Jackson expressed grief over "the murder of two sisters in our diocese". The Rev Greg Plata, who worked with Merrill and Held, said: "These were the two sweetest sisters you could imagine. It's so senseless."
Merrill and Held were part of a group of 20 parishioners who met regularly for worship at St Thomas the Apostle Catholic Church in Lexington, Mississippi, about 16km west of Durant. Both were nurse practitioners who worked with the Lexington Medical Clinic, where they helped treat thousands of patients a year regardless of their ability to pay, the Clarion-Ledger reported.
