Days after a 17-year-old was shot to death in Atlanta’s Old Fourth Ward neighborhood, the family member accused of killing him is behind bars.

Calvin Jackson Jr. was killed by his cousin in his own bedroom, the teen’s mother, Tawanna Brooks, told The Atlanta Journal-Constitution. Jamarion Ivory, 18, was arrested in Clayton County two days later and charged with felony murder, according to police.

The deadly shooting happened Saturday afternoon at Jackson’s home in the 300 block of Parkway Drive, authorities said. Atlanta police were sent to the apartment just before 2 p.m. and found Jackson suffering from a gunshot wound. He was rushed to the hospital, but later died of his injuries.

Calvin Jackson was a junior at Atlanta's Grady High School, according to a GoFundMe page.

Jackson, a rising junior at Atlanta’s Grady High School, was one of five children and Brooks’ only son. She said he and Ivory were close, and that she opened her home to her nephew following his mother’s death several years ago.

She isn’t sure what led to the shooting, but said she never would have allowed a gun inside her home. She was at work Saturday afternoon when she received the news that no mother wants to hear.

“I was at work and I got that phone call that said he had been shot by our own family member,” Brooks said through tears. “I was helping him out. He was staying with us at the time ... I don’t know why he would do something like that.”

Arrest warrants were issued for Ivory the day Jackson was killed. He was captured in Clayton County on Monday and has since been booked into the Fulton County Jail, online records show.

A GoFundMe page has been set up by the community to help cover Jackson’s funeral expenses. As of Thursday evening, the page had raised more than $12,000.

Meanwhile, Brooks said she and her daughters are absolutely devastated. The grieving family is still staying in the apartment where the shooting occurred, but everything inside the home reminds them of Calvin.

“It’s just so different with him not being here right now,” Brooks said. “It don’t even feel right.”
