Lincoln police are looking for two brothers of a man who was recently arrested on suspicion of murder.
Police say 26-year-old Terrance Ice and 27-year-old Julius Ice had allegedly tampered with a key witness in their brother's investigation.
Twenty-five-year-old Austin Ice was arrested on suspicion of murder in the death of 42-year-old Rodrigo De La Rosa. Two boys discovered De La Rosa's remains along West Old Cheney Road in March.
The witness tells police the Ice brothers tried to attack her at her home on June 20. She says the men were unable to get in, but one of them made a threatening gesture.
