Cadenbach, had a $100,000 bond issued for his arrest in connection with a previous domestic violence dispute, but on Saturday afternoon when he met with his mum and two sons at the park, he told his mum that “he wasn’t going to be taken alive”.
Police said Cadenbach left the park in his mum’s car with the two boys, and then she called police to report the kidnap and car jacking.
A helicopter overhead saw someone moving towards the vehicle and officers moved toward the scene, but they immediately heard gunshots, police said.
Officers say Cadenbach shot and killed his children.
"He was apparently shooting his children. We tried to engage him and it appears he took his own life,” said St. Louis County Police Department's Deputy Chief Kenneth Cox.
A family member said:
"A mother who was trying to protect her children, will now have 2 funerals for these babies. These babies also have 2 older siblings as well.
