An argument over a spilled drink is what led to Sunday afternoon's shooting at the Circle K gas station on Shallowford Road that left a 59-year-old man dead, according Hamilton County court records.
The suspect, 37-year-old Barry Maples, was also charged in connection to an earlier homicide - the Easter Sunday killing of Allan David Rice.
On Sunday, just after 4 p.m., Chattanooga police were called to the Circle K gas station and found the victim, whom police have not yet identified, lying on the floor with multiple gunshot wounds, court records show.
The man was taken to a local hospital, where he later died.
Surveillance footage showed a man enter the gas station and shoot the victim several times before fleeing on foot, court records state.
Witnesses at the scene told police the victim had not shown any aggression toward the perpetrator before the shooting.
Maples was found nearby in an open field. A backpack and two firearms were located near him, and the shell casings found at the scene matched the caliber of the handguns, court records allege.
He was taken to the police service center for questioning, and he told police he had been arguing with the victim just before the shooting, allegedly over the man pouring out his drink, court records allege.
"Mr. Maples then confessed to shooting [the victim] because [the victim] had 'disrespected him,'" investigators wrote in court documents.
Maples also confessed to killing Rice, who was gunned down on April 12 at the Speedway gas station on Bonny Oaks Drive, court records state, though no motive was listed.
After confessing, Maples "gave details about shooting Mr. Rice that only the suspect and police would have known," investigators wrote. And evidence was found that "directly links Mr. Maples to the homicide of Allan Rice."
Sunday afternoon's homicide is the city's fourth gun-related killing this year.
