Darrell Wanye Caldwell, Jr., 19, was taken into custody Tuesday night and charged with aggravated robbery with a deadly weapon.
Police believe he was driving a black Nissan Maxima that pulled up alongside a woman at the intersection of Highway 820 and Campus Drive last week.
Caldwell and his armed accomplice forced the woman to follow them to a Goodwill parking lot. They robbed her and let her go, police said.
In a second, similar incident, police said a woman was shot in the foot.
In that incident, Temika Risher and her 15-year-old daughter were driving home when they saw a car sitting at the corner of Anglin Drive and Loop 820 with its brake lights on.
Risher says he started shooting.
"That split second, I just smashed the gas and took off," she said.
She managed to drive about a mile until a Forest Hill police officer saw her.
That's when her daughter realized Caldwell shot Risher in the foot.
Risher says she was relieved to learn of Caldwell's arrest.
"Ain't nobody else have to get hurt," said Risher.
Officers tracked Caldwell down after finding his black Nissan Maxima abandoned in a field.
He is not cooperating with the investigation so the identity of the second suspect is still unknown.
Anyone with information is encouraged to call Crime Stoppers at 817-469-TIPS.
