A Bibb County judge on Friday denied bond for Frank Reeves, the 73-year-old man suspected of shooting a woman to death outside a Macon gas station.
Judge Howard Simms said the testimony and evidence in the case indicates that Reeves is unstable and unpredictable.
He said all evidence in the case pointed to "an unprovoked and violent assault" on 65-year-old Linda Hunnicutt.
He also wrote that, before the Dec. 4 shooting, Reeves' family had begun guardianship proceedings for him.
He said he found that "troubling" and could not rule that Reeves did not pose a threat to others.
Reeves reportedly shot Hunnicutt December 4 after her car and his motorized wheelchair bumped in the parking lot of the Murphy's Express Gas station on the Gray Highway in East Macon.
His lawyer on Thursday argued that Reeves does not pose a threat to the community, is not a threat to flee and also should be released due to his health.
Citing the defendant's "advanced age and physical infirmities," Simms' order directed the Bibb County sheriff's office to ensure that Reeves gets proper health care and access to his counsel.
Reeves remains in the Bibb County jail, charged with felony murder.
