Police found Alison Munson, 31, dead in her home Dec. 19 about 9:30 p.m. Police previously said they received information that Pryor had harmed Munson, and that he possibly was headed to his home in the Smithsburg area.
Deputies en route to the area of Pryor's house on Welty Church Road asked the Smithsburg Police Department for assistance.
Nicholson, the only Smithsburg officer on duty, responded to the request and was waiting for backup in a driveway off Welty Church Road when he was confronted by Pryor and shot
Pryor faces first-degree murder charges in the deaths of Munson and Nicholson. Prosecutors have filed a notice of intention to seek the death penalty if Pryor is convicted of Nicholson's death.
A grand jury in February handed up three separate indictments against Pryor. One charges him with Munson's death, and he is charged in a separate indictment with Nicholson's death.
The third indictment includes four charges of attempted first-degree murder and other crimes for his involvement in a shootout with police who tried to take him into custody in the area of the historic Ringgold Meeting House in Ringgold, about a mile and a half from the fatal shooting site.
All of the cases arose from a "continuing course of conduct" and arose out of the same incident, prosecutors wrote in the February motion to consolidate.
Deputy State's Attorneys Joseph Michael and Steven Kessell and Assistant State's Attorney Viki Pauler represented the state Tuesday.

Katy C. O'Donnell, division chief of the Office of the Public Defender's Capital Defense Division, and Assistant Public Defender Brian Hutchison represent Pryor.
