“On June 2, 2020 at 8:13 P.M. the 2-year-old male identified as Jameson Long, died at Children’s Mercy Hospital in Kansas City, MO while being treated for his injuries. An autopsy will be scheduled for this investigation. The child abuse investigation is ongoing.”

Authorities arrested Brian O’Grodnick, 22, on Sunday. He’s been charged with four counts of felony child abuse. The Joplin Police Department confirmed that O’Grodnick was not the victim’s biological father.

Investigators obtained a search warrant of O’Grodnick’s cellphone and discovered that he recorded previous instances of child abuse, according to court documents. On April 22, O’Grodnick allegedly pinched Jameson’s mouth together while shoving his face.

On April 21, the suspect allegedly pinched the boy’s mouth together again and slapped him across the face. On April 22, cellphone footage showed O’Grodnick choking Jameson while forcing the boy to beg for water. In another video on the same day, the suspect allegedly punched Jameson in the face.

On May 1, cellphone footage showed O’Grodnick grab Jameson’s hair while demanding to know if the boy loved him, according to a probable cause statement obtained by KSN.

“Do you love me?” O’Grodnick asked the boy, according to police.

Throughout the videos, Jameson can be seen bruised, shaking, and crying, investigators said. Police added that the suspect admitted to abusing the boy while recording the incidents with his cellphone.

O’Grodnick remains behind bars without bond. Upgraded charges are possible, pending autopsy results.

Meanwhile, a GoFundMe page has been set up to help family with funeral and burial expenses.
