Cellphone seized in Georgia prison among evidence in Bibb County’s latest homicide case

A Smith & Wesson cartridge casing was plucked from a tire on the ambulance that carried Jonathan Demarcus Risby to the hospital Friday where he died from multiple gunshot wounds.

He would have turned 25 next month.

The bullet casing was among dozens of pieces of evidence that Bibb County sheriff’s crime scene investigators collected in the few hundred yards between Fairview Avenue and Applewood Street, where Risby and 39-year-old Tavonya Gladys Smith were gunned down that morning.

Authorities are looking for 25-year-old Anterrio Tremaine Stinson in connection with the killing.

Emergency responders found $338 in cash in Risby’s pocket along with a white container containing “white rock material” that is believed to be drugs, according to an incident report obtained by The Telegraph on Monday.

Smith’s relationship to Risby is unclear. However, Quateshia Monsha Carswell, who was at the crime scene just after the shooting, told investigators she was Risby’s girlfriend.

Carswell was taken to the sheriff’s office annex building on Third Street for questioning, the report said.

Another piece of evidence collected in the case was seized from inside a jail cell at Washington State Prison by Georgia Department of Corrections officers.

A cellphone with two service cards hidden beneath the battery pack was reportedly found in the possession of inmate Kelvin Dewayne Carswell. It is unclear if he is related to Quateshia Carswell.

Kelvin Carswell is serving a 15-year sentence in connection with a 2012 carjacking.

According to Telegraph archives, he pointed a handgun at a man and pulled the trigger twice while the man was pumping gas at the Chevron on Riverside Drive one morning. The gun clicked, but no bullets fired.

The victim ran and Carswell drove off in the man’s rental car.

In 2012, The Telegraph reported that Carswell had been arrested 20 times since 1998.

Another man’s cellphone also was seized.

A ZTE brand phone belonging to Devontez Turner also was entered into evidence. Turner watched with a woman while investigators combed the scene Friday, but his connection with the case is unclear.

Anyone with information about this incident or Stinson’s whereabouts is urged to call the Bibb County sheriff’s office at 478-751-7500 or call Macon Regional Crimestoppers at 1-877-68-CRIME.
