A 21-year-old Olivia man pleaded guilty to 2nd-degree murder on Tuesday for the death of a toddler in his care in December of 2010. A judge will now decide the severity of the sentence for Sergio Turrubiates Junior, who faces the possibility of up to 20 years in prison. Turrubiates was caring for 19-month-old Tiana Moore in her mother’s apartment in Olivia on December 22nd, 2010, when the child suffered multiple blunt force trauma injuries to her head. She died 2 days later at Children’s Hospital in St. Paul. In court on Tuesday, Turrubiates pleaded guilty to an amended charge of child endangerment 2nd-degree murder without intent. Under the terms of the plea agreement, the original 2nd-degree murder charge, which had a maximum sentence of 40 years in prison, will be dismissed. Sentencing is expected to take place within several days.
