Ladd Stewart Robson was arrested in Springfield Wednesday night.
Springfield police say Robson was telling people inside Club 1444 he killed his half-brother.
Wednesday morning, Myrtle Point police found Lance Lucero with severe injuries. He later died at a local hospital.
“We immediately identified Ladd Stewart Robson initially as a person of interest and later as the suspect in the case,” said Paul Frasier, Coos County District Attorney.
Detectives from Myrtle Point spent the day collecting evidence from Robson’s car in Springfield.
Robson was formally arraigned Thursday afternoon.
