Here is a Hulk mask LoCO found online which may or may not be similar to the one worn by the suspects

Humboldt County Sheriff’s Office press release: 

On Thursday, April 21, 2016 at 12:30 a.m., Humboldt County Deputy Sheriffs responded to the Benbow KOA Campground for a report of an armed robbery. Deputies arrived on scene and spoke with the 32 year old female victim. The victim stated she met “Brian,” (suspect #1), because he stated he wanted to purchase the car she was selling. Brian left, claiming to return with cash for the vehicle, and returned with two other suspects. The victim told deputies all three of the suspects were armed with handguns, and a cattle prod style stun device. The suspects took approximately $9,000 in cash and fled in the victim’s vehicle and a lowered, dark green Honda sedan they had arrived in. Deputies searched the area and located the vehicle the victim was selling. The vehicle’s tires were slashed and its keys were missing. The suspects were not located.

• Suspect #1: is described as a black male adult, between 30-35 years of age, 6’ tall, with short black hair, and brown eyes, and goes by the name “Brian.”
• Suspect #2: is a black adult, 5’5” tall, wearing a green “Hulk” mask.
• Suspect #3: is a black adult, 6’ tall, also wearing a green “Hulk” mask.

Anyone with information for the Sheriff’s Office regarding this case or related criminal activity is encouraged to call the Sheriff’s Office at 707-445-7251 or the Sheriff’s Office Crime Tip line at 707-268-2539.

[LoCO Note: Did you find it odd that a person selling a car would meet up with strangers carrying $9,000 in cash? So did we. We spoke to HCSO PIO Selena Zorrilla-Mendoza who confirmed this was in fact the report taken by deputies. Strange, maybe!]
