COLUMBIA, S.C. -- The eighth suspect in the beating of a Columbia teen has been sentenced to 10 years in prison.
Yahquann Gantt, 19, was sentenced Thursday on charges of aggravated assault and battery, robbery and criminal conspiracy. Gantt will get credit for being in jail since his arrest in June 2011.
Carter Strange, 18, was attacked as he jogged through the Five Points area to get home before his parents' midnight curfew.
Police say Strange was attacked by four teens while four others were waiting in a nearby car and did nothing to stop or report the assault.
Vicki Strange told Circuit Judge Michael Nettles that her son's beating has changed her family forever.
"They don't know what our family has gone through. Until someone decides your child's life isn't worth anything, you have no idea how I feel," Vicki Strange said.
The eight teens were arrested after police released video footage of them roaming Five Points on June 20, the night of the attack. Video footage showed them following other people that night before they attacked Strange, said prosecutor Dolly Garfield.
"It is my belief that these individuals were roaming through Five Points looking for prey and Carter Strange was their prey," Garfield said. "Yahquann Gantt crossed the street to help herd the prey."
After the attack, more surveillance cameras were installed in the neighborhood near the University of South Carolina. There are more than 200 cameras there now.
Gantt apologized to the Strange family Thursday.
