I was watching Forensic Files a couple hours ago. A father was accused of killing her 9 year old daughter. The girl's mother was suspiciously disappeared years before the killing.
Meanwhile, the father was in a relationship with his new girlfriend whom his daughter did not like. One day, the father called the cops fearing that his daughter was kidnapped from his house on way to school. The police went out looking for her, but no lead tips available, even tips from the neighbors. That changed the focus of this story from an unknown assailant to her father. The police had her father's vehicles towed away for investigating.
They secretly planted a GPS device on his trucks. It won't take long (in the span of 4 days) when the father drove about 65 miles in a vast forest, and then go back through his hometown to nearby empty area. Know what he did? He felt that his daughter's first grave was not deep enough so he had to move the body 65 miles to another location - her second grave - but the GPS has tracked his every move and precisely counted time... It revealed that the father has spent 44 minutes digging up for his daughter's new grave 65 miles away from home. That's obvious.
The police finally got a lead and recovered the body from the grave. The physical evidences were there and went through extensive testings to confirm who was the killer. It turned out to be his father. The duct tape on her body and hair matched the ones he had at home, it also matched the tire tracks to his own truck at the graveyard, and plastic bags from the same place at his house. That was the final puzzle piece. The father plead not guilty but he was found guilty for first degree murder. He got 56 years behind the bars, that is not enough in my opinion. Back to the start, where was the girl's mother? The mother's brother felt that she was killed, too. Her body is probably somewhere under the foundation. The father worked on the foundation when he killed the girl's mother, I suppose.
Why?
He was very obsessed with his then girlfriend - now ex-girlfriend, way too obsessed. He acted like his ex was much more important than his own daughter's life. Remember the girl and the ex did not get along, so it might be the factor. He was crazy over his ex, so he went on killing a dear young life. I don't understand him, not at all. When his ex found out that he was in jail, he proposed to her, she feared for her life. She changed the locks and do everything to be safe from him.
Really sad story. Real sad.
