A Cavour man convicted of attempted enticement of a minor using the internet was sentenced on Monday to 10 years in prison. 40-year old David Farrell was indicted by a federal grand jury and pleaded guilty in March. The conviction stemmed from incidents in April of 2021 when Farrell knowingly used his cell phone to persuade and entice a 15- year-old female to meet with him at a hotel in Sioux Falls for the purpose of having sexual activity. Unknown to him, and before the criminal conduct occurred, an undercover law enforcement officer assumed the identity of the 15-year-old female online. Farrell was immediately turned over to the custody of the U.S. Marshals Service.
