Richmond Police said charges have been upgraded from assault to murder against Jeremy Rice, 21, of Richmond, after the victim he reportedly hit with his vehicle died Monday.
The Fayette County Coroner's Office said Joshua Childers, 22, of Lexington, died from injuries suffered Saturday night.
The Coroner’s Office also says that his death is being investigated as a homicide.
Richmond Police said they were called to the 200 block of Evansdale Avenue in response to a report of a pedestrian hit by a vehicle.
Upon arrival, officers said they learned a woman and her boyfriend, identified as Jeremy Rice, had been involved in a domestic argument in which Rice shoved her in the chest.
Police said the woman's brother, Joshua Childers, intervened in the altercation and a scuffle between the two men ensued and spilled from the apartment into the parking lot.
Police said Rice got into his vehicle and tried to leave and that Childers tried to prevent Rice from leaving by grabbing the vehicle door handles.
Investigators said Rice backed-up, shifted into drive and drove into Childers, who was in front of the vehicle at the time. Police said Rice fled the scene.
Police said Childers was unresponsive at the scene.
He was rushed to UK Hospital in Lexington with what police called a serious head injury that included a fractured skull with resultant swelling of the brain and internal bleeding.
Police said Childers underwent surgery at UK Hospital and was listed in critical condition up until his death on Monday.
Rice was located on Depot Road and taken into the custody the night of the reported incident.
He was lodged in the Madison County Detention Center.
The case remained under investigation.
