"The suspect pointed the handgun at the victim and demanded his wallet," Burbank Police Sgt. Derek Green said. "Fearing for his life, the victim ran away and was able to escape to safety."

During a preliminary investigation, three additional street robberies were reported within minutes of each other. All of the victims described the same dark-colored Kia as the suspect's vehicle.

The vehicle was spotted, and police found stolen property inside. Authorities subsequently detained a woman who is allegedly connected to one of the suspects.

Detectives later arrested Hicks and Tamburo at a home in Burbank. Hicks is accused of carrying out the armed robberies, and Tamburo is suspected of driving the vehicle that was used during the incidents.

Police say all of the robberies involved unsuspecting victims who were out for a walk.

The relationship between Hicks and Tamburo was not immediately confirmed, but photos posted on Tamburo's Instagram page indicated the two were romantically involved.
