In 1990, HBO released a chilling documentary of a little girl who had been so badly abused as a baby that she developed psychopathic behavior by the time she was adopted.

Tim and Julie knew something was deeply wrong with their adopted daughter Beth when she began killing baby birds as a child.

According to reports, Beth was violently sexually abused by her father until she was about 19 months old.

The toddler and her infant brother Jonathan had been left in their sadistic father’s care after their mother tragically died.

Fortunately, both children were soon taken out of their father’s care and placed in a loving home with their adoptive parents, Tim and Julie.

While Beth remained sweet and docile whenever her parents spoke with her, it didn’t take long before the pair realized Beth was deeply disturbed.

According to reports, not only did Beth exhibit strange sexual behavior at a very young age, but she also seemed to have a strong interest in violence and death.

Because her brother Jonathan also exhibited this behavior, but to a lesser extent, Tim and Julie set out to get some answers from the adoption agency.

For months, the agency refused to give the adoptive parents any information about their children’s past, which was reportedly meant to remain confidential.

After doing some digging, Tim and Julie finally discovered that both Beth and Jonathan had been severely physically abused by their father.

Beth, especially, had been violently sexually abused by her father until she and her brother were finally taken out of his custody.

In the bone-chilling documentary “Child of Rage,” which was released by HBO in 1990, Beth can be seen calmly explaining to her therapist, Dr. Ken Magid, how she enjoyed killing baby birds and molesting her brother.

Worst of all, Beth told the therapist with a completely straight face that she dreamt of murdering her parents and brother.

Tim and Julie, who were also interviewed, explained that no matter how many times they tried to talk to Beth, she never relented in her desire to kill them. Occasionally, they would find knives missing from the kitchen.

In one particularly brutal act of violence, Beth smashed her brother’s head into the cement outside, intending to kill him.

Fortunately, she did not succeed, but it became clear to Tim and Julie that their daughter wasn’t the least bit remorseful about what she had done.

Eventually Beth was diagnosed with a severe case of Reactive Attachment Disorder, a condition caused by extreme emotional or physical abuse that essentially prevents a child from being able to bond or connect with others.

Many children diagnosed with RAD exhibit extremely violent behavior that sometimes never goes away.

Beth’s behavior became so dangerous that she was eventually taken out of Tim and Julie’s care in April 1989 and placed into the care of Connell Watkins, a professional therapist.

Watkins took Beth in for about a year and gave her intensive behavior modification in hopes of training her to develop some form of empathy and remorse.

For several years, Beth stayed in therapy until, finally, she grew up to be a mentally stable and healthy woman.

Beth became so empathetic, in fact, that she later obtained a degree in nursing and authored a book entitled “More Than a Thread of Hope.”
