A Sioux Falls man says he robbed five convenience stores to support his family.
21-year-old Domach Khai gave a tearful apology to a judge Wednesday morning.
Khai was sentenced to 30 years in prison for a string of convenience store robberies last year.
Police say Khai made three anonymous tip calls to police with information about the robberies from a blocked phone number.
Those calls led authorities to him because the caller knew details authorities hadn't released to the public.
