OCEANSIDE, Calif. (AP) - Police in Oceanside, Calif., say the death of former NFL star Junior Seau  appears to be a suicide.
    
Seau, who was 43, was found shot to death at his home today. Police say his girlfriend reported finding him unconscious with a gunshot wound to the chest. A gun was found nearby.
    
His mother, Luisa Seau, was weeping uncontrollably as she appeared before reporters. She said, "I don't understand." She said her son had given no indication of a problem when she spoke to him by phone earlier in the week, and that he was "joking" with her.
    
Seau was a standout linebacker with USC before going to the San Diego Chargers and leading them to the Super Bowl after the 1994 season. The team says in a statement that everyone with the Chargers "is in complete shock and disbelief" over the news.
