RaeAnn and Stephen Gruver, whose 18-year-old son died at LSU last fall, will join 14 other parents who say that they have lost sons to college hazing on a Dateline NBC special on Sunday.

Billed as a look "behind closed doors on America's frat row" the program will include families of students from Penn State, Texas Tech, Florida A&M, Rider University and others speaking to with NBC News’ Andrea Canning. It will also include interviews with a current and former university president, fraternity brothers and a critic of Greek life, according to NBC.

Gruver, 18, was one month into his first year of college at LSU when he died in what authorities have described as a hazing ritual at a fraternity house.

RaeAnn and Stephen Gruver have traveled from their home in Roswell, Georgia, to the Louisiana Capitol multiple times this year to advocate on behalf of new anti-hazing laws that were signed on Thursday.

Police have said Gruver attended a fraternity initiation event and was forced to chug 190-proof liquor. His blood alcohol level was 0.495 when he died – more than six times the legal limit to drive.

Four former LSU students have been indicted in Gruver's death and have pleaded not guilty – one on a charge of negligent homicide and three others with hazing.

Phi Delta Theta fraternity has been banned from LSU's campus until at least 2033, following an investigation into the events that led to Gruver's death.

Dateline's "The College Fraternity Crisis" special will air on NBC at 6 p.m. Sunday.
