The victim has been identified as Antonio Martin. Police say Martin had pulled a gun on an officer who was conducting a routine check on a gas station. A woman identified as Martin’s mother said her son was with his girlfriend.

The mother says she was told her son was shot as he tried to run away. Protesters gathered at the scene of the shooting overnight, leading to three arrests.
