Izabella Santa Bujanda, 20, who worked at Animal Clipper, admitted to concealing BeBe by wrapping her with a towel and walking out the back door with her last Saturday, according to police.
When the pair heard the crime was getting news coverage, Barrera drove BeBe to a neighborhood in Las Sendas, possibly near Power and Thomas roads in Mesa, and dumped the tiny three-pound dog near a front yard of a house, police said.
The dog still hasn't been found.
Police said Barrera admitted to what he did.
Both Bujanda and Barrera have been charged with one count of felony theft, police said.
"I would just like the community to know that although I have some relief, I’m still wanting and needing my BeBe," Willingham said.
"Please keep an eye out for BeBe as she is still missing."
If anyone has seen or found BeBe, please call the Mesa Police Department at 480-644-2211 or call Silent Witness at either 480-WITNESS (948-6377) or 1-800-343-TIPS (8477).
