Jones’ family filed the lawsuit claiming negligence and alleging Drummond failed to exercise ordinary care in keeping people safe, Channel 2 reported.
The family’s attorney said Drummond should’ve employed off-duty police officers at the party as well as private security.
“Brandon died for nothing,” Ryan Jones told Channel 2, “and I’m not going to let my little brother’s death go in vain.”
Drummond was a wide receiver who played several seasons for the Detroit Lions, ending his career after the 2007 season with the Kansas City Chiefs.
He is known for hosting lavish celebrity pool parties at the home, described in previous event listings as the NFL Mansion.
