HAYWARD -- Two San Mateo men were charged with murder on Monday in the beating death of a Hawaii man whose body was found last month near an abandoned Hayward building.

Joseph Mataele, 22, and Sosaia Havili, 24, were arrested Thursday for the death of 29-year-old Marcus Antonio Brown, after investigators gained evidence linking both suspects to the slaying, said Hayward police Sgt. Mark Ormsby.

Police on Monday would not release details on the evidence and did not elaborate on the defendants' relationship with the victim as the killing remained under investigation.

On Monday, both defendants were being held without bail, Ormsby said.

During the early morning hours of Sept. 5, Brown's lifeless body was found behind an abandoned Hayward home.

On Sept. 4, the day before he was found dead, Brown hopped a flight to San Jose, police said. Flight records show he was slated to return home to Lihue, Kauai, on Sept. 5, police said.

At some point after landing at Mineta San Jose International Airport, he made the 28-mile trek north to Hayward.

Police said they're not sure what Brown did in the hours that followed, but they do know that about 2:15 a.m., a passer-by found his body on the back patio of a vacant home in the 1400 block of B Street. He was lying face down and had major head trauma, police said.

Brown was carrying no identification when his body was discovered outside the boarded home in an area police and neighbors say is frequented by transients.

An autopsy by the Alameda County coroner's office revealed that Brown had been dead for less than 24 hours when he was discovered, police said.

Police at first believed Brown was a vagrant who frequented the downtown area but learned his true identity after a female friend in Hawaii reported him missing to San Jose police on Sept. 7.

Born in Virginia, Brown was a U.S. Army veteran most recently employed as a vacuum salesman in Hawaii. At the time of his death, he was married, Ormsby said, but was separated from his wife.

He was a bike enthusiast who belonged to a motorcycle club called "Ganggreen," owned a 2000 Kawasaki ZX-9R and loved race cars and drag racing.

He is survived by family including his wife, Christine Brown, of Honolulu; son Marquise Crawley of King George, Va.; and daughter Selah Brown of Honolulu.
