Lexington police say on December 21st a man matching the picture you see to the right of the screen knocked on an elderly man's door asking if he knew a neighbor.
"The victim said 'no, i don't know who you're talking about,'" Detective William Persley says.
"He probably came by to see if there was anyone else in the residence besides the victim. Once he discovered the victim was alone and an elderly gentleman, he knew he was a prime target."
Persley says it was only moments later that the man came back to the door. This time, he pushed the victim out of the way and demanded money.
Police say the victim never saw a weapon, but felt threatened enough to hand over the cash in his pocket.
Police say the suspect then shoved the elderly man to the ground and took off.
Police hope you can help them identify the man in the composite sketch so they can make an arrest in this robbery.
