A 35-year-old man accused of robbing four visitors at gunpoint in Manoa made his initial court appearance in Honolulu District Court on Thursday.

Quadralis J. Watson appeared before Judge Kenneth Shimozono on charges of first-degree robbery and four firearm offenses including ownership of an automatic firearm. His bail is set at $250,000.

Police said four tourists from California were driving in the Manoa area and stopped on Kaloaluiki Street at about 6:10 a.m. Monday to take photos of the mountains.

A black Mercedes sport utility vehicle pulled over and blocked them in, according to court documents detailing the robbery.

Two to three male suspects, one of which was later identified as Watson, jumped out of the SUV.

Police said Watson pointed a handgun at the tourists and said, “Give me everything you have. … You guys only have 10 seconds to give everything.”

One of the other suspects allegedly took the visitors’ belongings from them as well as their property in their vehicle. The culprits then fled in the SUV.

Police issued an all-points bulletin on the robbery and vehicle description.

Police later that day spotted a black Mercedes SUV on Kuhio Avenue occupied by two men including Watson.

Police arrested him on suspicion of robbery after the victims positively identified him.

Police did not arrest the other man, described by Hawaii News Now as Isaiah McCoy, a former death row inmate exonerated of a drug-related murder in Delaware.

Last year in Hawaii the government dropped a sex-trafficking case against McCoy.

In 2011 Watson, also known as “Danger,” was convicted in federal court of sex trafficking involving a teenage girl from August 2007 to March 2008. He was sentenced to 10 years in prison.

State criminal records show he has a felony conviction for promoting a dangerous drug and misdemeanor convictions for assault, terroristic threatening, driving without a license and violating a temporary restraining order.

Watson also has petty misdemeanor convictions for prostitution, promoting a detrimental drug, harassment, disorderly conduct and theft.
