JACKSONVILLE, Fla. -

Graduates of Andrew Jackson High School walked in honor of 20-year-old Shelby Farah, who was killed during a a robbery one week ago in the Brentwood Area.

They gathered at the school and walked to the Metro PCS store on North Main, where police said Farah was shot and killed.

The group laid flowers at the doorstep of the store and joined hands in prayer, asking for God to give the family strength.

It has also been a trying week for Farah's mother, Darlene, who spent hours waiting outside the Jacksonville Sheriff's Office for Farah's killer to be found.

"After I sat there and camped out and did what I did because I wanted to see him. I wanted to see him face-to-face," Darlene said. "I wanted to be the last face he saw, just like he was the last face Shelby saw. Because if it was me, Shelby would've done it for me."

"This gathering is about showing solidarity between our Andrew Jackson classmates and family," said organizer Marc McCullough. "I'm from the class of '88, and there's various classes out here from 2013 on back, and we want to show that we're family and if one of us falls, we have your back. So the organization we started is called 'Tigers Got Your Back.'

Farah's family said her funeral will be held at Paxon Revival Center with Pastor Dobbs at 10:30 a.m. Saturday. The viewing will be Friday night from 5 to 7 p.m., also at Paxon Revival Center.

Prosecutors are seeking the death penalty in the case against Farah's accused killer, 21-year-old James Rhodes.

Rhodes is expected in court again on Aug. 14.
