A 35-year-old woman identified in surveillance photos as Sandtisha Gardner faces charges in connection with a series of thefts from employees at the University of Texas Health Science Center.

UT system police began investigating the cases in September, after an employee reported that someone had stolen his laptop computer and iPod from his work cubicle when he went out to lunch, according to an arrest warrant affidavit.

Several other workers also reported thefts during that month. Also among the items stolen from them were wallets and purses containing credit cards, and a cellphone, the affidavit stated.

In November, police obtained surveillance pictures from a department store where one of the credit cards was used and aired them during a Crime Stoppers segment, the affidavit stated.

Detectives with St. Mary's University then contacted UT system police, saying that they recognized the woman in the photos as Gardner, the affidavit stated.

According to that document, Gardner and two other people had been linked to similar crimes on the St. Mary's University campus.

Although Gardner was taken into custody in connection with that case in November, a theft charge related to the UT case was added Thursday.
