The robbery just happened to occur when the clerk went in the back of the store?

Gas stations get robbed so often, you would think they would be more vigilant. What I am more curious about is if in this incident and the one at Sacred Heart, does law enforcement know if these are repeat offenders?

HCSO Press Release:

On 10-08-2014, at approximately 2:00 a.m., the Humboldt County Sheriff’s Office received a call of an armed robbery which just occurred at the 76 Gas and Mini-Mart 2698 Central Avenue, McKinleyville. The clerk reported that two suspects, one armed with a knife had entered the store, stole cash from the register and fled northbound on Central Avenue.  Deputies arrived on scene within a minute of the call being dispatched and began searching the area for the suspects.

The investigating deputy met with the clerk who told the deputy he had momentarily entered a back office when the store was empty. When the clerk exited the office, the first suspect ran into the store and told him to stay in the office as the suspect went to the cash register. A second suspect entered the store immediately behind the first suspect and was brandishing a buck knife with an approximate six inch blade. The suspects stole money from the cash register and fled the store.

The suspects were described as follows:

Suspect #1 – dark hooded sweatshirt with the hoods pulled up to conceal the face, and dark pants
Suspect #2-  white male adult, approximately 6” 2’,  around 30 years old, light colored hair, wearing a blue bandana handkerchief covering his face, a navy blue sweatshirt and armed with a buck knife
