Criminologists said crimes involving children killing their parents are rare, yet some studies show those crimes are on the rise.

“It's difficult to think that our children would kill us,” said Howard Kurtz, Sociology and Criminal Justice associate professor at Southwest Oklahoma State University.

Kurtz said four recent Oklahoma homicide cases involving children accused of killing their parents go against the norm.

“It's much more likely that a parent would kill their child than a child kill their parent,” Kurtz said.

The latest case is Christian Costello, accused of stabbing his father to death at an Oklahoma City Braum’s.

Last October, investigators in Duncan said Alan Hruby killed his parents and sister in the family home.

Investigators said the parents were cutting off Hruby financially and he got mad.

Kurtz said what shocks him is the level of violence in those cases, especially when knives were used.

“When people use a knife, they have to get right up with someone, they have to get close and personal with them,” Kurtz told News 9.  “A lot of times, there is a lot of anger involved in it."

There are three theories criminologists apply to crimes like these: the child has a mental health issue, the child was being abused or the child was born a sociopath.

“In all these cases, if you could sit down both with the children and the surviving parents and find out, what went wrong, if something went wrong at all,” Kurtz said.

The suspects in all these cases are male.

Kurtz said statistics show males commit more crimes than females.
