The trial for the man charged with killing Brooklyn resident Mollie Tibbetts in 2018 has been delayed again. Cristhian Bahena Rivera had been scheduled to stand trial for first-degree murder on February 4 in Sioux City.  That plan became uncertain last week when Judge Joel Yates suspended the case so that the Iowa Supreme Court could decide whether to grant Rivera’s pretrial appeal of a key ruling. A court spokesman said Tuesday (1/28) that the trial has been delayed and will not happen in the month of February. A new trial date will be set after the Iowa Supreme Court decides how to handle Rivera’s appeal.
