A man sentenced to life in prison without parole after a murder plea has successfully withdrawn his guilty plea and will have his case heard again, according to court documents. Saul Castillo entered a guilty plea Aug. 24, 2015, in the malice murder case surrounding Silverio Acosta’s death two years earlier. Acosta was shot multiple times in the chest, head and hand on Father’s Day 2013 after a Tadmore Park soccer game in Gainesville.
