The father of an 8-year-old boy who died Thursday afternoon faces a Level 1 felony charge of neglect of a dependent resulting in death, police said.

Curtis Gilbert Collman Jr., 41, of Seymour had been held on a charge of failing to register as a sex offender since shortly after his son, Curtis Collman III, was found not breathing and unresponsive at his grandparents’ home near Crothersville.

He also faces charges of pointing a firearm and possession of methamphetamine.

Jackson County Sheriff Mike Carothers declined to discuss the basis for the new charges but said police expect to issue a news release at noon today.

The news release comes as police await toxicology reports in hopes of determining the cause of death of the child. Carothers said he expects those results within two weeks.

He said an autopsy conducted Friday at Schneck Medical Center in Seymour was inconclusive.

“That will hopefully give us more about what happened,” he said Saturday.

Collman III was described as being full of life and enjoyed riding his bicycle, watching “SpongeBob Squarepants,” watching “Minecraft” tutorials and playing with Nerf guns and video games, according to his obituary published in Monday’s Tribune.

The boy spent Wednesday night with his father at his Seymour home, where he had recently moved, Carothers said.

The Collmans arrived at the Crothersville home around 1 p.m. Thursday, police said.

Officers with the Jackson County Sheriff’s Department and personnel with Jackson County Emergency Medical Services were called to the scene at 1:47 p.m. Thursday and administered CPR, Carothers said.

He said Collman Jr. had custody of the child.

The neglect charge is punishable by 20 to 40 years in prison upon conviction.

The failure to register as a sex offender charge stems from his 2006 conviction on a Class D felony of sexual misconduct with a minor in Jackson Circuit Court.

He was sentenced to six years in prison on that charge Sept. 28, 2006. He was released Aug. 13, 2009, after serving nearly three years of the sentence.

On Thursday, Collman was booked into the Jackson County Jail in Brownstown at 8:03 p.m. Thursday. He was being held without bond pending his initial hearing on the new charges.

A pretrial on the failure to register as a sex offender charge has been set for 9 a.m. Aug. 17 in Jackson Circuit Court. His bond was set at $1,500 on that charge.
