Police are hoping you can help name the suspect in a Sioux Falls robbery.
They say the suspect robbed a woman at knifepoint Monday afternoon in the Hy-Vee Parking Lot near 57th and Cliff.
Authorities say he got away with her purse.
The suspect is described as possibly Native American.
Police did find the Dallas Cowboys sweatshirt the suspect was wearing.
If you have any information in the case you should call Crime Stoppers.
In the meantime, do you know how to keep yourself safe if you find yourself in this situation?
Put yourself in this picture. Someone with a knife approaches you in a parking lot and takes off with your purse.
While no one ever wants to be in this situation, there are some tactics you can put into practice every day to protect yourself.
Community Resource Officer Brady Lieuwen says one of the best things you can do is pay attention to your surroundings.
For example, if you're loading groceries in the back of your car police say you should look around you every now and then.
"Take a couple quick glances around and don't get fixated on one task," Officer Brady Lieuwen said.
You'll also want to take note of what the people around you are doing.
"If they're generally walking to the store, their head's down. If they're looking at you and looking around your vehicle and looking at what's going on they might be trying to size you up," Lieuwen said.
But what if it's too late and you're already being attacked?
"Obviously if you have your phone on you and you're able to, call 911, but if not just start screaming, making noise, yelling for help," Lieuwen said.
Officer Liewen says a crime of this nature--a random attack--doesn't happen very often in Sioux Falls, which is encouraging.
"We have to remember that the city is getting bigger and we have to keep our head on a swivel and just be aware of what's going on around us at all times,"Lieuwen said.
If you are attacked here's another way to help officers. Even though it is a traumatic situation, try to remember as much about the suspect as possible, such as facial features.
Hy-Vee says is working with law enforcement in the investigation.
A spokesperson called the case and "unfortunate situation" and said the safety of employees and customers is "of the utmost importance."
