A Salt Lake man charged with murdering his girlfriend's little boy faces a trial next month in 3rd District Court.

David Carl Huston, 29, pleaded not guilty to second-degree murder in the death of Dillon Seth Moss, 15 months, who died of "baby shaking syndrome."Judge Frank Noel scheduled a trial for May 18.

According to preliminary hearing testimony, Moss was in Huston's care on Jan. 7, the day that Huston took the unconscious child to a convalescent center at 1430 E. 45th South. Huston told nurses that the boy had fallen out of a crib, witnesses said. The child died the following day in Primary Children's Medical Center.
