Kayleigh Slusher, a three-year-old girl in Napa, California. The little girl lives with her mother and the mother's boyfriend, while the real father is in prison. During this time, the police often came to the house to visit and check on the welfare of the little child and make sure everything was okay, the mother was also monitored. On January 30, Kayleigh's body was found in a suitcase in a freezer left for three days, the child's body was also found with bruises and sexual assault, the mother (Krueger) and her boyfriend Ryan Scott Warner were arrested at El Cerrito Bart Station near a restaurant. Police report that there were several calls reporting that the parents were using drugs and not feeding little Kayleigh, although police also indicated that the home was a safe environment for the child and that he was not There was no indication of abuse, police did not contact child protection due to lack of evidence of any kind. The mother and her boyfriend are charged with “assault on a child, causing the death of the little girl and both admitted to killing the little girl. Both charges include special circumstances while prosecutors await information. before condemning the mother and boyfriend. The news also states that both will be sentenced to 25 years to life in prison if convicted. As for Kayleigh's body, it will be returned to the family (grandparents) and relative, the funeral will be held in a private service in memory of the death which was caused by the mother and boyfriend.After researching this story by Kayleigh Slusher, the three criminological theories that would be appropriate for this:Attachment: In the book on p. 96-97, Attachment studies...... middle of paper ......ng his daughter. He also advised me that failing to care for a child in this case and allowing the boyfriend to do anything to the child amounts to negligent homicide and voluntary manslaughter. In my conclusion, I think the boyfriend should not be sentenced to 25 years to life in prison, but a death sentence, I can understand that a person kills another person who is also an adult like you, but it she is a child, a three-year-old little girl who knows nothing, incapable of living her life to the fullest. The boyfriend showed no remorse, the mother cried, but she also believes she is neglecting her own daughter. Krueger and her boyfriend went too far for what they had committed, there should be no mercy, so in conclusion by what the mother and her boyfriend had done, having intentional homicide, negligent homicide, and without showing any remorse for this crime, death penalty.
