A surveillance video shows a suspect gunning down a convenience store clerk in metro Phoenix over a pack of cigarettes before calmly stepping over the victim and fleeing.

The chilling depiction was outlined in a court document Friday as a judge set bail at $1 million for 29-year-old Apolinar Altamirano in connection with the shooting of the 21-year-old clerk during an overnight shift.

Altamirano was convicted in 2012 on a burglary charge but never went to prison after getting probation.

The store where the shooting occurred banned Altamirano from the location two weeks ago.

In arguing against bail, the prosecutor cited the fact that the suspect is in the country illegally along with his criminal record.
