MEMPHIS, Tenn. -- Police are on high alert for three heavily armed robbers.
In surveillance photos, the robbers are seen wearing Halloween masks and armed with police-style rifles.
According to investigators, their latest crime happened at the BP gas station on Rockcreek and Highway 64.
“I guess crime doesn't have an area code and that's what's really astounding,” said Brittney Pencarinha, who works nearby.
Police say the suspects walked into the convenience store Monday night with assault rifles and held up the place. They ran off after they got the cash.
“I'm really scared,” said Pencarinha.
She isn’t the only one frightened by the three masked robbers armed with weapons that could kill dozens in just seconds.
Memphis police supervisors sent a memo to its officers alerting them to be cautious, especially if they're near the gas station that borders Cordova and Lakeland.
“It's so close to me. What if that would have been me? It could happen to anyone,” said Pencarinha, who says she’ll keep an eye out.
She'll watch for odd behavior because the surveillance photos show covered up faces.
“That's the scariest part. They could be out there casing up the next place,” said Pencarinha.
Pencarinha says she's warning her co-workers to be careful while the three suspects are still on the streets.
“You're either going to choose your life or your job, choose your life,” said Pencarinha.
Police believe the robbers also hit up the Motel 6 off Interstate 40 two weeks ago. It’s not known if one of the guns used was stolen from a MPD squad car last week.
