San Antonio police arrested 22-year-old Jessica Foster Wednesday night in connection with a robbery at a Speedy Mart on Highway 281 at Nakoma.
According to an arrest affidavit, Foster confessed to robbing a convenience store early Monday and bragged about committing a crime after seeing herself on the news.
Police said she fired a shot inside the store, demanded cash and walked out with the money.
Police also believe Foster was involved in a robbery at a Walgreens on San Pedro Avenue on Saturday.
Investigators have not charged Foster with any other crimes but the affidavit stated she is a person of interest in four other crimes.
