Did My Daughter Lie About Her Father Molesting Her?

Jill and her ex-husband, Brent, claim their 14-year-old daughter, Kendall, smokes marijuana and has falsely accused family members of abuse. Two years ago, Kendall accused her mother and sister, Lyndsey, of hitting her and her stepfather, Anthony, of threatening her. Six months later, Kendall also accused her father of physical abuse. Kendall now claims her father sexually abused her. Her family members adamantly deny all of her accusations. Jill and Anthony say they cannot keep Kendall at home because they fear she will make more false accusations against them -- so they allowed her to live in another apartment. Dr. Phil analyzes each allegation with the family. Is there any truth to what Kendall alleges?
