Police say the boy's grandmother who had been watching him while his mother was at work, called around 1 p.m. to report the child had been taken. They say she took 3-month-old Brandon Cuellar inside a bedroom while she was unloading groceries from her car. In a matter of a few minutes, the infant was taken and gone, according to police.
Officers say the grandmother did not see the suspect enter the apartment.
Police released a video clip that shows the man walking down the sidewalk holding a baby carrier covered by a white blanket.
"The family does not recognize this suspect," police said in a Twitter post.

San Jose police says the child's father is incarcerated and out of the picture.
Police say no Amber Alert was called due to the lack of suspect vehicle information. FBI Child Abduction Response Team is now involved in the investigation and every resource is being used to find Cuellar.
"Today, someone's walking around with a child they didn't have yesterday," SJPD Sgt. Christian Camarillo said.
A cash reward is being offered in return of the infant.
SJPD tweeted out images of the suspect. They say the male suspect entered a residence in the 1000 block of Elm Street and left with the infant in the carrier.
