The Honolulu Medical Examiner’s office has identified the homeless man who was stabbed to death last Friday morning at Kailua District Park as 58-year-old Robert Coleman, Jr. Forty-eight-year-old Brian Kim was arrested and charged with second-degree murder. He remains in custody on $250,000 bail. He's expected to enter a plea in Circuit Court July 29. Police say the stabbing stemmed from an argument between the two homeless men. Kailua residents held two meetings at the park not far from where Coleman was killed last week and established a neighborhood security watch program.
