Investigators need help finding a woman who has been going on shopping sprees with other people's money.

The woman has passed several fake checks near downtown Houston, officials said.

Detectives said surveillance video at a Target store along the Katy Freeway near Sawyer captured images of the woman as she used the bogus checks.

The woman has used the names Elizabeth Luna, of Houston, and Elizabeth Olguin, of Victoria, officials said.

Investigators said they think the woman made the checks with fake names and fake addresses but used real account numbers. Detectives said they think she got the bank account numbers by stealing real checkbooks.

The woman may be working with other people, officials said.

Anyone with information is asked to call Crime Stoppers at 713-222-TIPS.
