Unarmed Security Guard Fatally Shot By Robbery Suspect In Northeast Miami-Dade (VIDEO)

An unarmed security guard was shot and killed early Friday morning by a would-be robber, police say.

The incident happened just east of Miami Gardens at the Vista Palms apartments at Northeast 191 Street and Third Avenue, just east of Miami Gardens.

Investigators say a woman had arrived home at the complex when an armed man approached her in the parking lot and demanded her personal effects. The woman managed to escape as an off-duty security guard came to her aid.

Witnesses told WSVN they heard two gunshots as the woman fled the confrontation. The security guard was found dead by police minutes later as the robbery suspect escaped.

Miami-Dade police say they are searching for at least one suspect who is armed and dangerous. Anyone with information on the incident is urged to notify the authorities.
