NELSON — A worker at a quiet mobile home park in northern Portage County where a 1-year-old boy was allegedly killed Saturday, said the boy and his mother moved into the neighborhood about two months ago.

Early Saturday morning neighbors were awoken to police lights from emergency vehicles that filled the neighborhood’s narrow streets. The rumor going through the crowd was the baby had “overheated.”

Police say Nicholas J. Catazaro, 26, of 9924 Green Drive, Windham, killed the boy by throwing him against a wall.

Catazaro was arraigned on a murder charge Tuesday in Portage County Municipal Court in Ravenna and is being held on a $1 million bond. If convicted, Catazaro faces a sentence of 15 years to life in prison.

According to a complaint filed with the court Tuesday, the incident happened Friday night at a mobile home at 9882 Bayberry Lane, just north of Nelson Ledges Quarry Park.

Portage County sheriff’s deputies were called to the address at about 12:30 a.m. Saturday along with an EMS squad for a 1-year-old boy who was not breathing, according to the Portage County Sheriff’s Office, which said CPR was being performed on the child when deputies and EMS arrived. The boy was pronounced dead at University Hospitals Portage Medical Center Saturday. Catazaro was arrested Sunday.

An autopsy by the Cuyahoga County Medical Examiner’s office found that the boy had a fractured skull.

An obituary placed Tuesday with the Record-Courier for Leon Chehin-Merryman, 1, of Garrettsville, matches a birthdate for the victim listed in court records. Leon’s parents are Jacob Merryman and Ashlyn Chehin.

The relationship between Catazaro and the boy was not publicly known Tuesday.

Catazaro did not speak during the hearing. Judge Barbara Oswick also imposed other conditions requested by Assistant Prosecutor Jared Smiley, including that if Catazaro is released on bond, he would be ordered to have no contact with the boy’s family, their property or any other juveniles. He also would be required to wear a GPS monitoring device.

“Based on the seriousness of the offense charge of murder,” Smiley said, “and in consideration of the defendant’s actions of throwing and dropping a 13-month-old baby and ultimately killing him, this defendant, if released, poses a significant risk to the community and to the children of the community.”
