The couple is seen in front of a snake tank at Elliott's for Pets in the 6700 block of Brockton Avenue last Friday at about 8 p.m.
The man opens the tank, reaches in and grabs a small red-tailed boa constrictor. He hands it to the woman, who is visibly pregnant.
The woman, with the snake in her hand, walks out of the store with the male suspect.
