His was the most prominent of recent suicides by former NFL players.

(Seau) "Take me. Leave my son. But it's too late."

Luisa Seau in May after former chargers linebacker Junior Seau shot himself. Although one examination of his brain showed no damage, Seau's family wonders if further research may reveal a disease brought on by hits to the head.

(Easterling) "I believe the NFL suppressed the information."

Mary-Ann Easterling is the widow of Ray Easterling, an ex-Atlanta defensive back who killed himself in April. He had chronic traumatic encephalopathy.

(Danias) "It's tragic any time you have a loss of someone who was part of the NFL family."

NFL attorney Anastasia Danias points out the league has become more pro-active to prevent brain damage. Easterling says her husband regretted playing football for a living.

(Easterling) "Considering the last year of his life, he would not have done it."

Ray Easterling is among more than 2,000 former players in a lawsuit against the NFL which has asked a Philadelphia judge to dismiss the case.
