A billboard in northeast Omaha asks for help in solving the 10-month-old slaying of 37-year-old Darrell Taylor.
It says: "Who killed our dad?" It carries a phone number for Omaha Crime Stoppers and promises a reward.
Taylor was gunned down early in the morning on the day after Christmas and died at the scene in northwest Omaha.
Son Darrell Taylor Jr. said his father was a good dad and "took care of his family and everybody."
Police says there are no new developments in the Taylor case.
