Timothy A. Adarna, 19, was charged yesterday with second-degree murder in the death of his stepfather, Robert Ramos, whose body was found Nov. 16 in the bedroom of his burned home on Kilipoe Street in 'Ewa Beach.

Jim Fulton, spokesman for the city prosecutor's office, said Adarna's bail has been set at $200,000, and his initial court appearance is scheduled for Monday.

An autopsy determined that Ramos, 55, bled to death after being stabbed in the neck and struck on the head and chest with a blunt object. The cause of death was listed as a homicide, according to the report.

Adarna "faces life in prison with the possibility of parole on the murder charge," said Fulton. "He faces up to 20 years on the arson charge."

Neighbors told police that Ramos parked his truck at his home shortly before 10 a.m. on the day of the fire and ran into the house. They said they heard Ramos arguing with someone, then saw a man fitting Adarna's description come out of the house and ride away on a bicycle.

The fire was noticed a short time later. Fire investigators said an accelerant was used to start the blaze that began at 10:07 a.m.
