Authorities say a 27-year-old man turned himself in to Fort Lauderdale, Florida, police after his mother recognized him in surveillance video circulated by detectives who were looking for a suspect in a string of four drug store robberies. The suspect would act like he was going to pay for an item, then punch or push the cashier when they opened the cash register, grabbing cash and running off.

A police report says Keith Fitzgerald Knowles Jr. told investigators his mother showed him the video footage of the robberies and he admitted that it was indeed him. Apparently, she convinced him to do the right thing… or else.

Knowles was booked into jail and remained in jail with bond set at $45,100. He’s charged with robbery, theft and battery on a person over 65.

Investigators had released the videos showing a series of robberies at Walgreens stores across Broward County in hopes of tracking down the suspect.

Jail records don’t list a lawyer for Knowles, who remains in custody. He is suspected of two other robberies.
