For the last 7 or so years, the atomic-ranch-era front of this 1929 bungalow at 1710 Welch St. served as the Scott Childress Studio, a hair salon. If you recognize that name, you likely know at least the outline of the rest of the story that goes with it: Childress was found on the floor of the property one Friday morning this past January, beaten to death with a pipe wrench; his roommate, Reginald Eaglin, was charged with the murder. The home was listed for sale in late February, but there’s a contract pending now. How that ends likely depends on a planning commission hearing scheduled for this afternoon. Up for approval: plans by Carnegie Homes to replace the modern-front house and the 2 apartments behind it — all on 7,500 sq. ft. — with 4 townhome lots along a central drive.
