VISALIA, Calif. (KSEE/KGPE) - Prosecutors have revealed the link between the two children kidnapped in Tulare County earlier this week and one of the suspects, detailing that one of the suspects was biologically related to the victims. According to the Tulare County Sheriff's Office, the two suspects allegedly involved entered the Earlimart home on Monday where the two young children (aged five and six years old) were staying, and took them. That prompted an Amber Alert to be issued early Monday morning for Fresno County, Kings County and Tulare County. 3 arrested after children kidnapped from Earlimart, deputies say The DA's office reports that one of the suspects, 29-year-old Makenzie Morrelli, was the children's biological mother and her custody rights had been terminated.

Officials say that Makenzie Morrelli gave herself up to law enforcement at around 4 a.m. and the children were returned safely.
