Since Mandy Steingasser's murdered body was discovered in 1993, authorities have been trying to bring her killer to justice. Prosecutors were hoping that day was approaching as they outlined their case during opening arguments last week against Joseph Belstadt, the man accused of killing Steingasser. The proceedings came to an end yesterday when Judge Sara Sheldon declared a mistrial due to concerns over the potential impact of the coronavirus. Rick Pfeifer, who has been covering the proceedings for the Niagara Gazette, says a new trial could begin this fall. In the meantime, Belstadt remains free on bail.
