Curtis K White Jr, 18, of Allie Mae Road, Cedar Grove and Ladell Alverez Faucette, 22 of Apsley Drive, McLeansville are both charged with two counts of first-degree murder and one count of robbery with a dangerous weapon.
The shooting happened around 4 p.m. at The Week in Treasures store in Cedar Grove.
Fifty-two-year-old storeowner Phillip Johnson was pronounced dead at the scene. A customer, 68-year-old Alexander "Skip" Wade - a retired Orange County investigator, was taken to Duke Medical Center where he later died.
White and Faucette allegedly took a cash drawer with $200 from the store.
Investigators have also charged White and Faucette in a robbery the day before at a Sam's Food Mart located at 6321 U.S. Hwy. 70 West in Mebane. According to warrants obtained by ABC11, they threatened a clerk with a gun and took a cash drawer with $500 in it.
Both White and Faucette are being held in Central Prison for safekeeping because Wade was a former deputy.
