Savaii Seau, brother of late Chargers star Junior Seau, killed in car crash

SAN DIEGO -- Officials have identified the 56-year-old driver killed in a collision with a dump truck in a San Diego suburb as Savaii Seau, the brother of late Chargers star and NFL Hall of Famer Junior Seau, according to the San Diego Union-Tribune.

Seau was driving in the suburb of Lakeside on Tuesday afternoon when his Audi drifted into a southbound lane and smashed into a water district truck, according to the newspaper. California Highway Patrol officials could not be immediately reached for comment.

The newspaper reported that Seau was not wearing a seat belt. He died after being taken to a hospital. Seau's wife was with him and suffered minor injuries along with the driver of the truck, according to the California Highway Patrol and a family member who spoke to the newspaper.

Investigators said they do not know whether drugs or alcohol were involved in Tuesday's crash and were awaiting results from toxicology tests, which could take months.

"Seau taught physical education at a private school that runs from preschool to eighth grade. He also coached flag football, basketball and track at its middle school campus, and was an accomplished artist who taught art in the school's summer programs," said Raymond Volker, the headmaster at Warren-Walker.

"The hearts of the entire Warren-Walker School community are heavy as we have lost a great human being, teacher and friend today," the headmaster said in a statement.

Junior Seau played 21 years as a linebacker with the Chargers,Miami Dolphins and New England Patriots. He died by suicide in 2012 and was found to have chronic traumatic encephalopathy, or CTE, which can only be diagnosed after death.

Junior Seau was a 10-time All-Pro and 12-time Pro Bowl selection, and was posthumously elected to the Pro Football Hall of Fame in 2015.
