On Friday night, officers responded to a CVS on East Yosemite Parkway around 8:30.
The man in the surveillance photo allegedly pulled out a gun on the clerk who handed over $200.
About 12 minutes later, officers received another call at a nearby AM-PM on Coffee Street.
The suspect allegedly pulled out a gun and demanded cash from the clerk - also making off with $200.
Witnesses say the suspect fired the gun inside - which is believed to be a pellet gun.
If you recognize the suspect in the photo or know anything about the robberies, you're asked to call Merced police.
