A Fresno convenience store clerk was gunned down at the Super 1 Food Store on Tulare between First and Cedar.
At least two suspects walked in around 11:00 p.m. Thursday night while two employees were working.
One of the workers was shot and the other was hit in the head with a blunt object.
Police are looking to see if it may have been a botched robbery that triggered the violence.
Detectives are interviewing the second clerk who is recovering at Community Regional Medical Center.
The names of the victims have not been released.
