KSAT-12 has the story:
The suspect allegedly walked into the Delicious Tamales restaurant on the 3500 block of South Presa Street, pulled out a gun and demanded cash from a store employee.
Police said the man took an undetermined amount of cash along with a dozen tamales before locking the employee in an oven.
The oven was not turned on, according to investigators, who said police arrested the suspect in the 100 block of Arlington Court with evidence linking him to the crime.
I wonder what that evidence was. Husks?
And the next question is, If they were "delicious" tamales, why take only a dozen?
