The only survivor of this week's mass shooting in South Carolina by former NFL player Phillip Adams has died of his injuries, authorities said Saturday.

Details: Robert Shook, 38, an air conditioning technician from Cherryville, North Carolina, died of gunshot wounds from Wednesday's shooting at a doctor's home in Rock Hill, S.C., which claimed the lives of five other victims.

The big picture: Adams killed himself after opening fire, authorities say.

• The other victims were physician Robert Lesslie, his wife, Barbara Lesslie, and their grandchildren, Adah Lesslie, 9, Noah Lesslie, 5, and GSM Services air conditioning technician James Lewis — who was working with colleague Shook when the shooting happened.

Of note: The Rock Hill shooting is the latest of several mass shootings to hit the U.S. over the past month.
