A 59-year-old homeless man was charged yesterday in the killing of a 70-year-old homeless man in a church parking lot in Manoa.

David Orpin was charged with second-degree murder. He was being held at the main station in lieu of $100,000 bail.

Police said Orpin walked to the HPD’s main station on Beretania Street at about 2 a.m. Wednesday and said he might have killed a man in a church parking lot in Manoa.

Officers went to St. Pius X Church on Lowrey Avenue and found a man’s body in the back parking lot.

Police said the victim might have been beaten about five hours before Orpin approached officers.

The Honolulu Medical Examiner’s Office has not identified the victim, but determined he died of head injuries from blunt force trauma.

Detectives do not know whether a weapon was used in the beating.

On Sept. 22 a homeless man was arrested following the stabbing death of another homeless man at the corner of Kapahulu and Kalakaua avenues. Authorities determined the stabbing was self-defense and released the suspect.

Darlene Hein of the Waikiki Care-a-Van program said studies show homeless people are not more likely to be violent than anyone else.
