A 33-year-old man who was shot and killed in a Yigo neighborhood last month died from a gunshot wound to his torso, according to the results of an autopsy released by the Guam Police Department.

An autopsy was performed on the victim, Keith Castro, on Sunday – two weeks after the deadly shooting occurred.

His death has been ruled a homicide, said GPD spokesman Sgt. Paul Tapao.

The two men arrested in connection to his death were indicted in the Superior Court of Guam on Friday.

Joshua Rivera Palacios, 37, was indicted on charges of murder as a first-degree felony with a special allegation of possession or use of a deadly weapon in the commission of a felony.

Thomas Mark Taitano, 28, was indicted on charges of four counts of aggravated assault and two counts of criminal mischief to a motor vehicle, each with a special allegation of possession or use of a deadly weapon in the commission of a felony. He was also charged with eluding a police officer as a misdemeanor.

Palacios is being held on $500,000 cash bail. Taitano’s cash bail was set at $100,000.

Both are scheduled to be arraigned on Aug. 14.


Police launched the shooting investigation on July 28.

Officers found Castro unresponsive along Chalan Tun Fred Cabesa in Yigo. Investigators learned he was in the area to sell a pickup truck.

Taitano allegedly struck Castro with a baton as the pair fought, court documents state.

Castro was able to get away for a brief moment but slipped and fell, documents state.

Taitano allegedly continued to hit Castro with the baton before Palacios allegedly shot him once, documents state.

Police learned the following day that Taitano allegedly tried to run over three people with his car in Dededo, documents state. He was also accused of damaging one of the victims' vehicles after he allegedly rammed his car into it.

Both were out on parole at the time Castro was beaten and shot.

Adult Probation Services has told the court Palacios is a high risk to the public and listed his prior convictions during the hearing. His convictions were for: theft and criminal trespass in 2007; theft of property in 2010; second-degree robbery in 2012 and burglary in 2013.

Taitano was previously convicted of arson.
