Guam - Guam Police confirm a local gang involved in underground fighting sparked a triple homicide in Harmon over the weekend. Police say the gang confronted a group of guys in a truck at the Hanna Market in Harmon Saturday evening. A riot broke out and a teenage victim was allegedly stabbed and killed in the parking lot. 

Just hours later early Sunday morning authorities say the gang was drinking alcohol - celebrating their fight at this abandoned warehouse near the Dededo Flea Market. That's when another fight broke out and two individuals who lived nearby were attacked. The two were also stabbed and killed.

Crime scene investigators spent the day looking for clues and conducting interviews, and Sunday evening arrested four adults and two male teenagers. Three of them stood before Judge Alberto Tolentino for a magistrate's hearing this afternoon. First up was Vimson Menisio.  The judge informed him that he was being charged with aggravated murder as a first degree felony, two counts each with a special allegation of possession and use of a deadly weapon in the commission of a felony. "You are also charged with rioting as a third degree felony and a special allegation of possession and use of a deadly weapon in the commission of that felony, as well," said his honor.

Menisio is being held on a $1 million cash bail, along with the second murder suspect, Benny Sam Robert, who was on pretrial release for similar charges he faces today. he was charged with aggravated murder as a first-degree felony with a special allegation of possession and use of a deadly weapon in the commission of a felony, with rioting as a third degree felony and a special allegation possession and use of a deadly weapon in the commission of that felony.

The prosecution contend both face life in prison for the aggravate murder charge. A third suspect, Osupwang Jery Muritok, also on pretrial release for rioting and aggravated assault is being held on $100,000 cash bail. Judge Tolentino said, "Muritok did commit the offense of rioting in that he did knowingly participate with four or more others in the course of disorderly conduct with the intent to commit for facilitate a commission of a felony…Muritok did knowingly possess and use a deadly weapon - that is a knife - in the commission of a felony that is rioting as a third degree felony."

Each also charged with jurisdiction over an adult, as a 16-year-old boy was also confined at the Department of Youth Affairs for two counts of rioting, conspiracy, and under age consumption, while a 15-year-old boy was charged with aggravated assault, two counts of rioting, conspiracy, and underage consumption. The fourth adult suspect, Jeff Pedro, charged with rioting was released, because the AG's Office states his involvement is still under investigation.

The three men in court today have a preliminary hearing set for September 22 at 4pm.
