Curtis Collman is charged with the death of his 8-year-old son, Curtis, Jr., in addition to facing charges for pointing a firearm, theft and failure to register as a sex offender, WAVE-TV reports.
On June 21, investigators said the second grader started eating what he thought was breakfast cereal on a plate after telling his father he was hungry.
Instead, police said the boy was eating crystal meth. By the time he was done, Curtis had consumed 180 times the lethal limit.
"Just your worst nightmare as a parent," Jackson County chief deputy prosecutor Jeffrey Chalfant said.
The boy's father allegedly threatened a female friend at gunpoint when she tried to call 911 for help. Prosecutors said he even stopped his own parents from getting help for the boy, who was having seizures and convulsing.
"A 8-year-old child more than likely suffered for many hours," detective Tom Barker said. "It upsets you."
Investigators said the elder Collman's previous record includes charges for trafficking and sexual misconduct with a minor. He was also arrested by police once for a high-speed chase.
The suspect is seeking to have his bond reduced to await trial at home. Prosecutors say they're going to fight to keep him behind bars.
