A former Arapahoe County social worker convicted of filing a false child abuse claim against an Aurora city councilwoman pleaded guilty Tuesday to charges related to her lying about having brain cancer during her initial criminal case. Robin Niceta, 42, pleaded guilty to criminal impersonation, forgery, tampering with physical evidence and attempting to influence a public servant, according to the Arapahoe County District Attorney’s Office. Niceta was arrested after she called in a fake tip in January 2022 against Aurora Councilwoman Danielle Jurinsky after Jurinsky criticized Niceta’s then-partner — Vanessa Wilson, who was Aurora’s embattled police chief at the time — on a talk radio show.
