CEDAR FALLS, Iowa (AP) — Two men already jailed in connection with a botched 2019 robbery that led to a man’s death in Cedar Falls are now charged with first-degree murder.

Authorities said Monday that charges were upgraded for 20-year-old Keyon Christian Roby and 22-year-old James Wright-Buls in the death of 24-year-old Grant Saul.

The two men were already being detained on conspiracy and robbery charges in connection with the killing.

Saul was shot to death at a downtown apartment on Dec. 4, 2019.
